In this study, we report UV-MALDI-TOF MS evidence of a fullerene-like silsesquioxane, a high-symmetry polyhedral oligomeric silsesquioxane (POSS or SSO) formulated as R-SiO or T (T = RSiO). The T preparation can be performed using a normal hydrolytic condensation of [(3-methacryloxy)propyl]trimethoxysilane (MPMS) as an example. Theoretically, four 3sp³ hybrid orbitals (each containing an unpaired electron) of a Si atom are generated before the bond formation. Then it bonds to another four atom electrons using the four generated hybrid orbitals which produced a stable configuration. This fullerene-like silsesquioxane should exhibit much more functionality, activity and selectivity and is easier to assemble than the double bonds in a fullerene.
在本研究中，我们报告了一种类富勒烯倍半硅氧烷的紫外基质辅助激光解吸电离飞行时间质谱（UV-MALDI-TOF MS）证据，这是一种高对称性的多面体低聚倍半硅氧烷（POSS或SSO），其化学式为R-SiO或T（T = RSiO）。以[(3-甲基丙烯酰氧基)丙基]三甲氧基硅烷（MPMS）为例，可通过常规水解缩合制备T。理论上，硅原子在形成键之前会产生四个3sp³杂化轨道（每个轨道包含一个未成对电子）。然后，它利用这四个生成的杂化轨道与另外四个原子电子结合，形成稳定构型。这种类富勒烯倍半硅氧烷应表现出更多的功能性、活性和选择性，并且比富勒烯中的双键更容易组装。
