英文摘要	In this paper, a series of novel active silicone-oligomers (PMDM) of high refractive index (RI) with dual reactive moieties (Si-H and S-H) synthesized by nonhydrolytic sol-gel condensation are reported for the first time. The RI of the oligosiloxane can be effectively increased from 1.55 to 1.65 by varying the feed ratio between methyldimethoxysilane (MDMS) and 3-mercaptopropylmethyldimethoxysilane (MMDS). Additionally, via "thiol-ene" click chemistry and the subsequent hydrosilylation reaction under a Pt catalyst, a transparent siloxane-polymer film with enhanced refractive index (1.59) and excellent thermal stability (T-5% = 381 degrees C) was facilely synthesized and characterized, which in turn effectively substantiated the reactivity of the dual reactive moieties in PMDM. Such active oligomers would be useful chemical intermediates and the easily processed materials have great potential in modern optical/photonic applications such as waveguides, lasers or light emitting diodes.; Major Project of Beijing Science and Technology Program [Z141100003814011, Z151100003315023]; National Natural Science Foundation of China (NSFC) [51302006, 51303008, 51402006, 51573003]; SCI(E); EI; ARTICLE; zhangcuihong@pku.edu.cn; yuhaifeng@pku.edu.cn; yanghuai@pku.edu.cn; 75; 70825-70831; 6
