摘要

A new hairy rod-type conjugated polymer consisting of alternating N-alkylated diketopyrrolopyrrole diphenylene and alkoxy-substitued phenylene units in the backbone is described. The polymer exhibits a characteristic bright red photo- and electroluminescence with maximum at about 640nm. The luminescence behaviour is characterised in detail.
