We observed the electroluminescent behavior of films of the polydiacetylene poly[1,6-bis(3,6-dipalmitoyl-N-carbazolyl)-2,4-hexadiyne](polyDPCHD) by preparing organic light-emitting diodes (OLED) based on a single emitting polymer layer. We measured their optical and electrical characteristics and obtained a typical power efficiency of 10-6. The observed rapid quenching of the electroluminescence wassupposed to be related to the formation of charged traps enhanced both by local disorder of polymer chains and by current flow.

Abstract
We observed the electroluminescent behavior of films of the polydiacetylene poly[1,6-bis(3,6-dipalmitoyl-N-carbazolyl)-2,4-hexadiyne](polyDPCHD) by preparing organic light-emitting diodes (OLED) based on a single emitting polymer layer. We measured their optical and electrical characteristics and obtained a typical power efficiency of 10-6. The observed rapid quenching of the electroluminescence wassupposed to be related to the formation of charged traps enhanced both by local disorder of polymer chains and by current flow.File in questo prodotto:
