Comparison of Optical Properties of Porphyrin Dispersed Polyimide and Porphyrin Incorporated Polyimide into the Main Chain
Abstract Optical properties of polyimide film with dispersed metalloporphyrin (ZnTPDPI) and those of polyimide film containing tetraphenyl-porphyrinzinc in polymer backbone (POTPPI) were compared. For ZnTPDPI, the increase of the content of ZnTPP in PI film exhibited the increase of absorption and emission. POTPPI showed higher emission and absorption than ZnTPDPI. Relative fluorescence quantum yield of POTPPI was 0.218, while that of ZnTPDPI was 0.125.
