Novel fluorescent polyimides (PIs) were prepared from a new diamine, 4-(4-(4-amino-2-(4,5-diphenyl-1Hi-midazol-2-yl)phenoxy)phenoxy)-3-(4,5-diphenyl-1H-imidazol-2-yl)benzenamine(DA), and three tetracarboxylic dianhydrides. The PIs are amorphous and soluble in polar aprotic solvents and demonstrate a film-forming capability; their inherent viscosities ranged from 43 to 82 ml g−1. The PIs show emission in dilute (0.2 g per 100 ml) N,N-dimethyl acetamide solution with photoluminescence (PL) quantum yields in the range of 11–25%. The chemiluminescence (CL) activity of PIs in the presence of peroxyoxalate was also investigated.
