DOCUMENT TYPE: Journal CA Section: 66 (Surface Chemistry and Colloids) In the present study we used a combination of scanning tunneling microscopy and d. functional theory calcns. to examine the structures of 2,3-butanediol stereoisomers adsorbed on a Si(001)-2 ′ 1 surface at room temp. We found that most mols. prefer to adsorb on the bridge between the ends of two adjacent dimers within the dimer row; this adsorption preference differs from that of alkene-type mols., which undergo a cycloaddn. reaction with a Si dimer on Si(001) surfaces. Detn. of the abs. chirality of (R,R)- and (S,S)-2,3-butanediol adsorbates on Si(001) indicated that each mol. preserves its chirality during bonding to Si atoms. In addn., 2,3-butanediol preferred to adsorb in the CH3-gauche conformation rather than the CH3-anti conformation, which can be explained by steric considerations. These results suggest that alc.In this experiment, several chemicals are used like 7440-21-3 and 19132-06-0 -type org. mols. are useful agents for producing chirally modified Si surfaces. .
