FIG. 1.

Molecular structure of P[(por)A-S].

FIG. 2.

Time-integrated luminescence spectra of P[(por)A-S] films with porphyrin comonomer concentration of (a) 0.27% and (b) 0.1%, respectively, at the excitation wavelength of 400 nm and the pulses power of 3 mW.

FIG. 3.

Transient luminescence relaxation processes (points) of P[(por)A-S] films with porphyrin comonomer concentration of (a) 0.27% and (b) 0.1%, respectively, at the emission peak of about 650 nm. The solid curves are the calculating results of Förster-type bimolecular annihilation theory.

FIG. 4.

Interaction potential energy as a function of the rotation angle of the porphyrin molecules in dilute P[(por)A-S] film. represents the number of the phenyl groups between the intrachain neighboring porphyrin molecules.
