中文摘要to explore the reactivities of alkene (-ch=ch2) and carboxy (-cooh) group with h-si under uv irradiation, the addition mechanism for the reactions of sih3 radical with propylene and acetic acid was studied by using the b3lyp/6-311++ g(d,p) method. based on the surface energy profiles, the dominant reaction pathways can be established; i.e., sih3 adds to the terminal carbon atom of the alkene (-ch=ch2) to form an anti-markovnikov addition product, or adds to the oxygen atom of the carboxy group (-cooh) to form silyl acetate (ch3-coosih3). because the barrier in the reaction of the carboxy group (39.9 kj/ mol) is much larger than that of alkene (11.97 kj/mol), we conclude that the reaction of bifunctional molecules (e.g., omega-alkenoic acid) with h-si under irradiation condition is highly selective; i.e., the alkene group (-ch= ch2) reacts with sih3 substantially faster than the carboxyl group (-cooh), which agrees well with the experimental results. this provides the possibility of preparing carboxy-terminated monolayers on silicon surface from omega-alkenoic acids via direct photochemical reaction.
