Polymers with general formula {[(vpy)(2)vpyRe(CO)(3)(tmphen)(+)])(n){[vpy)(2)vpyRe(CO)(3)(NO2-phen)(+) ]}(m) (NO2-phen = 5-nitro-1,10-phenanthroline; tmphen = 3,4,7,8-tetramethyl-1,10-phenanthroline); vpy = 4-vinylpyridine) were prepared and their morphologies were studied by transmission electron microscopy (TEM). Multiple morphologies of aggregates from these Re-1 polymers were obtained by using different solvents. Energy transfer between MLCTRe -> tmphen and MLCTRe-NO2-phen, excited states inside the polymers was evidenced by steady state and time-resolved spectroscopy. Current Forster resonance energy transfer theory was successfully applied to energy transfer processes in these polymers.
