与传统的（甲基）丙烯酸酯化学反应相比，巯基烯反应是一种更耐氧的替代品，可以形成具有许多理想特性的光聚合网络，包括能量吸收、光学清晰度和减少收缩应力。然而，当使用市售单体时，许多巯基烯网络也表现出玻璃化转变温度（Tg）和交联密度等性能的降低。在本研究中，研究了将硅氧烷（SSQ）物种加入光聚合网络的有机/无机杂化硫醇树脂作为改善这些性能的途径。以可光聚合的单体[季戊四醇四基（3-巯基丙酸）（PETMP）或1,3,5-三烯丙基-1,3,5-三嗪-2,4,6(1H,3H,5H)-三酮（TATATO）]为溶剂，通过烷氧基硅烷水解/缩合化学方法合成了巯基和烯基功能化的ssq （SH-SSQ和烯基- ssq）。对得到的含ssq溶液（SSQ-PETMP和SSQ-TATATO）进行了表征，并对其在光聚合网络中的结合进行了评价。
The thiol-ene reaction serves as a more oxygen tolerant alternative to traditional (meth)acrylate chemistry for forming photopolymerized networks with numerous desirable attributes including energy absorption, optical clarity, and reduced shrinkage stress. However, when utilizing commercially available monomers, many thiol-ene networks also exhibit decreases in properties such as glass transition temperature (Tg) and crosslink density. In this study, hybrid organic/inorganic thiol-ene resins incorporating silsesquioxane (SSQ) species into the photopolymerized networks were investigated as a route to improve these properties. Thiol- and ene-functionalized SSQs (SH-SSQ and allyl-SSQ, respectively) were synthesized via alkoxysilane hydrolysis/condensation chemistry, using a photopolymerizable monomer [either pentaerythriol tetrakis(3-mercaptopropionate) (PETMP) or 1,3,5-triallyl-1,3,5-triazine-2,4,6(1H,3H,5H)-trione (TATATO)] as the reaction solvent. The resulting SSQ-containing solutions (SSQ-PETMP and SSQ-TATATO) were characterized, and their incorporation into photopolymerized networks was evaluated.
