Electron transport in fluorenylidene malononitrile doped polyester

Abstract
Electron mobilities have been measured in binary solid solutions of (4-n-butoxycarbonyl-9-fluorenylidene)malononitrile and a polyester. The temperature and electric field dependences of the mobility can be described as exp(T0/T)2 and exp(βE1/2), respectively. The results are discussed within the framework of a model involving hopping within a distribution of states broadened by disorder. A comparison of these results with those observed for hole transport in doped polymers is briefly discussed.
