Charge transport is one of the most important properties in organic materials.Charge transport properties of triphenylene discogens with a phenylpropionyloxy or 3-phenylpropenoyloxy side chain have been investigated computationally on the basis of semi-classical Marcus theory.The results show that three triphenylene derivatives have high charge mobility.Title compounds have much better electronic mobility than the triphenylene.The triphenylenes containing 3-phenylpropenoyloxy have better hole mobility,but smaller electronic mobility than the triphenylenes with phenylpropionyloxy.For the triphenylene discogens with a phenylpropionyloxy,the longer the alkloxy chains,the better the positive charge transfer rate,but the smaller the negative charge transfer rate.
