Abstract:
A two-step polymerization combining miniemulsion and solvothermal techniques was applied to synthesize tetraphenylethene-based nanoscale conjugated microporous polymers (TPE-NCMP), which simultaneously possessed a large surface area (1214 m2/g) and a high aggregation-induced florescence quantum yield (58%). Immobilization of Nile Red within micropores of TPE-NCMPs constructed a light-harvesting composite with characteristics of intense photons acquisition and efficient energy migration. Homogenous NCMP-based films were fabricated by blending the dye-doped TPE-NCMPs with PVA. The fluorescence emission could be flexibly tuned by varying the dosage of dyes over the whole visible spectrum including a pure white light.
