ABSTRACT: We report the synthesis, photophysical properties, and morphology of new star-shaped polymers with styrene-fluorene (St-Fl) conjugated moieties. Three polymers with different number of arms (P(St-Fl)n, n = 3, 4, and 8) were obtained by living anionic polymerization, and they exhibited a narrow molecular weight distribution (Mn/Mw
