A two-step polymerization combining mini-emulsion and solvothermal techniques was applied to synthesize tetraphenylethene-based nanoscale conjugated rnicroporous polymers (TPE-NCMP), which simultaneously possessed a large surface area (1214 m(2)/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.
