The steady-static and transient luminescence in porphyrin side chain polymer P[(por)A-S] doped in PMMA were studied by using transient and steady-state fluorescence spectroscopic technique.The results show that with the decrease of the interchain distance of P[(por)A-S]
the interactions of the porphyrins enhance which increase the nonradiating transition.As a result
the luminescence efficiency and the lifetime are inversely proportional to the interchain distance of P[(por)A-S].We also discuss the origin of the luminescence of P [(por)A-S] doped in PMMA.
