The synthesis, morphology, and photophysical properties of Poly[2,7-(9,9-dihexyl fluorene)]-block-poly(2-(Dimethylamino) ethyl methacrylate) (PF-b-PDMAEMA) copolymers invarious mixed solvents, i.e., THF/MeOH, DMF/MeOH, and 1,4-Dioxane/MeOH, with methanolcontents of 0, 10, 25, 50, 75, 90 vol.% were reported. TEM images showed that different aggregatemorphologies of PF-b-PDMAEMA, including spherical and large compound micelles, cylinder,nanorods, long stick-like structure, could be prepared by introducing different amount of methanolinto the copolymer/solvent system. The results indicated that aggregate morphologies ofPF-b-PDMAEMA, which obtained from various coil lengths and mixed solvents, had a greatinfluenced on the optical and photoluminescence properties of the prepared PF-b-PDMAEMAcopolymers
