In the past decade,bio-inspired chemistry using intricate and

organized biomolecules,such as peptides,proteins,viruses,and

enzymes,has demonstrated the marvelous power for assembling

and structure-directing small species into unique materials due to

their highly elaborate,self-assembling capability in nature,leading

to the emergence of unique physiological properties.1-3Recently,

anionic surfactants derived from diverse amino acids have been

applied to the synthesis of mesoporous materials.4In particular,

the use of a chiral anionic surfactant N-myristoyl-L-alanine sodium

salt enabled us to obtain a chiral mesoporous silica with a twisted

hexagonal rod-like morphology.5The usefulness of a polypeptide

as a template for assembling inorganic materials with a unique struc-ture has also been reported.6These accomplishments have inspired us to use amino acids in preparing materials unique in structure. The realm of artificial silica spheres has been extended by the emergence of an innovative synthetic method,the Sto¨ber method, which was reported in1968.7The need for silica spheres with a size of below100nm and two-or three-dimensionally periodic arrangement is constantly increasing because high-tech industries spur a tremendous demand for such silica spheres.8

Here we report the formation of the silica nanospheres with a size of12-23nm and with a well-ordered arrangement.Our method for forming the silica nanospheres is analogous to the so-called “Sto¨ber method”,7but basic amino acid monomers have been used in place of NH3;the hydrolysis and condensation reactions of tetraethyl orthosilicate(TEOS)as a silica source were carried out in the presence of L-lysine.

Various organic amines,such as biomolecules,polyamines,and polypeptides,can catalyze hydrolysis and polycondensation of TEOS in water,leading to the formation of controlled siloxane-based materials.9In this study,we successfully demonstrate that a simple amino acid monomer promotes the formation of silica, resulting in preparation of the well-ordered silica nanospheres. In a typical synthesis,L-lysine(0.146g,1mmol)was dissolved in the solution containing deionized water(139g)and octane(7.3 g)with stirring at333K.The pH of the resulting solution was in-creased to9.2.TEOS(10.41g,50mmol)was added to the mixture with stirring at333K.The final molar composition in the solution was1TEOS:0.02L-lysine:1.3C8H18:154.4H2O.The resulting mix-ture was stirred for20h at333K followed by being kept statically at373K for20h.Finally,the solution was directly evaporated in an oven at373K.Thus obtained silica was calcined in an oven at 873K to remove organic components,such as L-lysine and octane. High-resolution scanning electron microscopic(HRSEM)images of the silica product revealed that each silica micro-sized block with a size of1-3μm consisted of uniform-sized nanospheres with a three-dimensional array(Figure S1).Interestingly,the silica nanospheres with a uniform size of around12nm were well ordered (Figure1).The HRSEM image also revealed that there was a uniform nanospace between the nanoparticles,and that its size was estimated to be around3nm.Further structural characterizations were performed by high-resolution transmission electron microscopy (HRTEM)with the Fourier transform(FT)patterns(Figure2a-c).From HRTEM analysis,it is concluded that the arrangement of the silica nanospheres exhibited the ccp structure,Fm3h m space group.Although silica spheres with sizes of100-200nm have been easily obtained by the Sto¨ber method,to the best of our knowledge,silica nanospheres with a size of10nm arranged in a highly regular order is unprecedented.

The X-ray diffraction(XRD)pattern of the silica nanospheres is shown in Figure2d.This sample shows three X-ray diffraction peaks in the region of2θ)0.5-2.0°(Cu K R).Considering the HRTEM observations,these peaks can be indexed as the111,220, and331reflections based on the ccp structure.The nitrogen adsorption-desorption isotherms of the silica nanospheres after the removal of the organic moieties by calcination exhibit the type IV pattern(Figure S2).The BET(Brunauer-Emmett-Teller)surface area and the average pore size were found to be228m2g-1and 3.2nm,respectively.The uniform mesopores are attributed to the interstitial space between uniform-sized silica nanospheres.29Si MAS NMR measurements indicate that the product is highly condensed silica nanospheres(Figure S3).

Since the p K a’s of R-COOH,R-NH3+,and R-(CH2)4NH3+in L-lysine are estimated to be2.18,8.90,and10.28,respectively,

and the isoelectric point of L-lysine is9.74,10about92%of

R-(CH

)4NH2and33%of R-NH2would be protonated under the synthesis conditions(pH9.2).Herein,two kinds of interactions comprising the electrostatic one between anionic silicates(≡SiO-) and protonated amino groups in L-lysine and hydrogen-bonding between L-lysine molecules could be operative.The L-lysine molecules can cover the nanosphere surface in the growth process through the interaction of their protonated amino groups with the

silicates,leading to the control of the silica sphere size.Thus uniform-sized spheres would contribute to the well-packed structure with the assistance of the hydrogen-bonding interaction between L -lysine molecules.

TG-DTA measurements of the silica nanospheres before the calcination show the nearly same profile as that of L -lysine molecules (Figure S4).Combining the data from the CHN elemental analysis and the TG-DTA measurement of the obtained silica sample before the calcination,the contents of silica and L -lysine are estimated to be 15.02and 0.33mmol ?g -1,respectively;the molar ratio of L -lysine/SiO 2is found to be 0.022,which is consistent with the starting molar gel composition.

The influence of stereoisomer of the amino acid on the formation of silica nanospheres and their arrangements was also investigated.When D -lysine was used in place of L -lysine,the obtained silica was almost similar in the structural properties to those assembled in the presence of L -lysine (Figure S5).When the mixtures of L -lysine and D -lysine with varying proportions were used,the size of the uniform nanospheres was increased with increasing propor-tion of the opposite optical isomer.Finally,the use of the mixture of L -lysine and D -lysine at 50/50mol %gave well-ordered silica nanospheres with the largest size,and the size was found to be about 23nm by HRSEM images (Figures S6).These results indicate that the size of the silica nanospheres can be finely controlled between 12and 23nm by varying the optical purity of the amino acid.The details of the formation mechanism of the nanospheres and their arrangements are currently being studied.

Among 20types of essential amino acids in protein,L -lysine,L -histidine,and L -arginine are categorized as basic amino acids.We found that the use of L -arginine led to the formation of similar well-ordered silica nanospheres.On the other hand,the use of L -histidine was unsuccessful probably due to the relatively low basicity.Attempts to synthesize silica nanoparticles by using neutral amino acids,such as L -alanine and L -leucine,in combination with ammonia as a base catalyst were not successful either;XRD patterns and HRSEM images revealed that the obtained products from the control experiments were merely aggregates of silica particles without any regularity.It is concluded that the presence of amino acids with basicity,such as L -lysine and L -arginine,that have two amino groups in each molecule is indispensable for the three-dimensionally well-ordered arrangement of the silica nanospheres.Thus obtained well-ordered silica nanospheres having three-dimensional mesopores can serve as a template for fabricating the porous carbon replica,which are materials of great interest because of their potential applications to templates,electrodes,electric double-layer capacitors,and fuel cells.11,12We successfully prepared a well-ordered mesoporous carbon by using the obtained well-ordered silica nanospheres as a template.HRSEM and HRTEM images of the obtained carbon replica indicate the carbon replica has well-defined mesopores with the ccp structure,Fm 3h m space

group (Figure S7).The inverse contrast between the silica template

and the carbon replica was observed,showing the exact replication of the template structure with the symmetry being kept.XRD pattern and nitrogen adsorption -desorption isotherms also support the exact replication (Figure S9).

Thus we have discovered an interesting talent of a basic amino acid monomer for assembling silica nanospheres with high regular-ity,leading to the formation of a novel mesoporous material.In this case,basic amino acids worked to induce the orderly three-dimensional arrangement as well as a catalyst for the formation of silica.Our approach to preparing mesostructured materials by means of assembling nanospheres with regularity is not a general liquid-crystal templating method and will stimulate the development of a new family of ordered mesoporous materials.In addition to the novel silica nanospheres,success in the preparation of the carbon replica would offer the prospects for a wide diversity of applications.Acknowledgment.We thank Mr.S.Watanabe of Hitachi High-Technologies Corporation for HRSEM.This work was partly supported by Core Research for Evolutional Science and Technol-ogy (CREST)of JST Corporation to T.T.,O.T.,and Y.K.
