Abstract

Responsive PMO materials have been synthesized through co-assembly of bridged diacetylenic silsesquioxane and surfactant. The spatially defined polydiacetylenic component, mesoporous network, and the covalent proximity of polydiacetylene to silica endow the PMO with mechanical robustness, reversible chromatic responses, improved thermal stability, and faster responses to chemical stimuli. This research also provides an efficient molecular design and assembly paradigm to fabricate a family of conjugated optoelectronic materials, creating novel platforms for sensors, actuators, and other device applications.

摘要

通过桥连二乙炔基硅倍半氧烷与表面活性剂的共组装合成了响应性的金属有机骨架材料（PMO）。空间定义的聚二乙炔组分、介孔网络以及聚二乙炔与二氧化硅的共价接近性赋予了PMO机械稳健性、可逆的颜色响应、改善的热稳定性以及对化学刺激更快的响应。该研究还提供了一种高效的分子设计和组装模式，以制备一系列共轭光电子材料，为传感器、致动器及其他器件应用创造了新的平台。
