Characterizing the quenching process for phosphorescent dyes in poly [((n-butylamino) thionyl) phosphazene] films
Article Abstract:
The results of oxygen quenching experiments for four phosphorescent dyes [platinum octaethylporphyrin (PtOEP), platinum octaethylporphyrin ketone (PtOEPK), platinum tetrakis (pentafluorophenyl) porphyrin (PtTFPP), and Ru (dpp) 3Cl2 (dpp + 4,7-diphenyl-1, 10-phenanthroline)] in a low-glass-transition-temperature polymer matrix [poly [((n-butylamino) thionyl) phosphazene] (C4PATP) is compared. It is seen that oxygen diffusion in C4PATP obeys Fick's laws with diffusion coefficient of (3.7 + - 1.0) x 10 to the power -6 cm square s (sub -1).

Stacking of meso-tetrakis (3-N-methylpyridiniumyl) porphyrin on poly [d (A-T) 2]: importance of the distance between porphyrin's positive charges
Article Abstract:
The mseo-tetrakis (3-methylpyridiniuml) porphyrin complex at a ratio of 0.05 has been investigated by polarized spectroscopy. The spectroscopic properties of the complex depend on the NaCl concentration and time.
