Coordination of Hg2+ influences the electronic properties of the receptor at meso-position and alter the efficiency of nonradiative decay, hence increase the fluorescence intensity and red shift the absorption spectrum.展开更多

Consequently, we designed and prepared a new type borondipyrromethene(BODIPY) based porous organic polymer(POP) by using Sonogashira coupling reaction. This POP-1 exhibits high thermal stability with moderate surface area. In addition, POP-1 is highly emissive in a solid state. Due to enrichment of different kinds of heteroatoms in the skeleton of the porous polymer, POP-1 selectively captures carbon dioxide(CO_2) with relative high adsorption selectivity of CO_2/N_2.展开更多
