Summary:A series of N 1, N 4-didodecyl- N 1, N 4-diphenylbenzene-1,4-diamine-based polysquaraines have been synthesized under microwave irradiation in the absence of any catalyst. The effect of the solvent of polymerization, on the squaric acid catenation (1,2 and 1,3 linkages), has been studied and polysquaraines integrating linear chains in their backbone have been advantageously obtained by using di-functional alcohol during the polymerization. Such obtained polymers exhibit a broad emission with a quantum yield up to 18%. The latter were then tested in OLED devices exhibiting a promising white emission.
