Electron transfer
Perylenediimide derivatives have been incorporated as n-channel field-effect transistors due to their strong electron affinities. In particular, OFETs using highly packed perylene diimide derivatives with electron withdrawing groups such were found to have good air stability. Close molecular packing is important in retaining air stability. Electron transfer, on the other hand, was strongly influenced by the π-π stacking between perylene diimide units.
