我们已经开发了一系列新颖的整体材料,该材料基于以前在来宾-宿主系统中被视为掺杂剂的分子,以研究有机电光(EO)材料的内在结构与功能之间的关系。在具有变化的桥链段的EO分子库中,用双(叔丁基二苯基甲硅烷基)基团对供体的分子修饰导致非晶膜形成的改善并提高了极化效率。进一步修改以在桥上包括咔唑位点隔离基团,从而有效降低了分子间偶极-偶极相互作用,从而产生了极化效率约为3(nm V -1)2的材料,并将玻璃化转变温度提高到比报道的类似整体材料高20–40°C。该热稳定性水平可与普通的客体/主体系统相媲美,后者将聚甲基丙烯酸甲酯(PMMA)用作主体。我们的研究表明,π桥的长度和类型会影响发色团的第一个分子超极化率β,这在EO响应中得到了反映。这些发现进一步促进了整体材料因其增加的EO行为和改善的热稳定性而变得有用,从而使该材料系统成为商业应用中宾主系统的竞争者。

excellent agreement between the theoretical and experimental beta values demonstrates that a linear relation exists between the hyperpolarizability and the bondlengthalternation. An electrooptic coefficient, r(33), of approximately 25 pm/V at 1300 nm, for compound 4, incorporated into a polymer matrix, is competitive with organic chromophores. Moreover, this r(33) is more than 30 times larger than the previously

The silica-supported aqueous-phase catalyst (SAPC) approach has proven convenient for efficiently performing the hydration of alkynes with HgSO4/H2SO4 to give the corresponding carbonyl compounds in dichloromethane undermildconditions. The use of this solid reagent significantly improves the reaction work-up as it merely involves filtering and evaporating the solvent.
事实证明,二氧化硅负载的水相催化剂(SAPC)方法可方便地在温和条件下有效地将炔烃与HgSO 4 / H 2 SO 4进行水合,从而在二氯甲烷中生成相应的羰基化合物。该固体试剂的使用显着改善了反应后处理,因为它仅涉及过滤和蒸发溶剂。
