Preparation of Soluble and Fluorescent Poly(Arylene)S by 1,3-Dipolar Polycycloaddition and Properties of the Polymers
1,3-Dipolar polycycloadditions of 2,3,5,6-tetramethylterephthalodinitrile oxide with 3,6-diethynyl-9-hexylcarbazole or 2,6-diethynylpyridine afford novel soluble poly(arylene)s. The polymers show strong fluorescence in solutions as well as in cast films with peaks at 340-490 nm.
