Hollow microporous organic networks were prepared by using silica spheres as the template and tris(4-ethynylphenyl)amine and 2,6-diiodo-9,10-anthraquinone as the building blocks for the Sonogashira coupling. The resultant materials bearing triphenylamine and anthraquinone moieties showed efficient visible light absorption and catalytic activities in the photochemical oxidative coupling of benzylamines. Through the comparison studies of hollow and nonhollow catalytic materials, the diffusion pathway effect of the substrates was clearly observed in the photochemical conversion of benzylamines.
以二氧化硅球为模板，三（4-乙炔基苯基）胺和2,6-二碘-9,10-蒽醌为用于Sonogashira偶联的结构单元，制备了中空微孔有机网络。所得带有三苯胺和蒽醌部分的材料在苄胺的光化学氧化偶联中表现出高效的可见光吸收和催化活性。通过对中空和非中空催化材料的比较研究，在苄胺的光化学转化中清楚地观察到了底物的扩散途径效应。
