5-(3-Aminophenyl)-10,15,20-tri(4-methylphenyl) porphyrinato Pd (II) and Pt (II) complexes (2a-Pd) and (2a-Pt), respectively, were prepared from 5-(3-nitrophenyl)-10,15,20-tri(4-methyl-phenyl)porphyrin via two-step reactions, and reacted with cyanuric chloride to produce corresponding porphyrin derivatives (3a-Pd) and (3a-Pt)with a dichlorotriazine ring. Aromatic polyimides were prepared using diamine (4); triazine dichlorides having porphyrin units ( 3a- Pd), (3a- Pt),(3c-Pd), and (3c-Pt); fluoro-functionality 6-(p-perfluorononenyl oxyanilino) triazine- 2,4- dichloride (6); and tetracarboxylic dianhydride (5) in N-methyl-2-pyrrolidone (NMP) at an elevated temperature up to 300 degrees C. The resulting viscous polymeric solution was cast on a glass plate, affording well-proportioned reddish transparent films with number-average molecular weights of 25,000-38,000. Glass transition temperatures of the polymers were similar to 230 8C; the films were stable up to 400 degrees C in air. The film emission spectra showed a broad peak similar to 670 nm, similar to those of porphyrins(2a-Pd) and (2a-Pt) dispersed in a polystyrene matrix. While the luminescence of these polymer films was quenched with oxygen, it rapidly recovered under a deoxygenated atmosphere. The polyimide film sensitivity to oxygen was higher under low oxygen concentrations than those of porphyrins (2a-Pd) and (2a-Pt) dispersed in polystyrene. (C) 2017 Wiley Periodicals, Inc.
