英文摘要： Photofunctional polymers structured with porous organic framework would be developed at multiple dimensional scales. A diversity of photofunctional groups are applied to construct or decorate the porous organic frameworks and their composites in order to create the multiple components and hierarchical structures at the molecular level or nano/micro/macro scale. It is therefore anticipated that the resulting materials would promise great potentials in the energy/environment applications such as optical responsiveness, light harvesting, photo catalysis and optical sensing. The typical porous organic frameworks, covalent organic frameworks (COFs) and conjugated microporous polymers (CMPs), are studied herein. The photo sensitive COF is designed at molecular level to achieve the light-induced pore-on and pore-off. The preparation of core-shell structured CMP is planed and the mechanism of photon capture, transfer and transduction among the chromogenic units would be revealed within the hierarchical structures. The macroscopic CMP gel is pursued and combined with high-performance carbon materials for optimization of optical energy usage and transduction due to host-guest interactions.
