Abstract

New organic semiconductor molecule 2,5-diphenyl-1,4-distyrylbenzene (trans-DPDSB) was synthesized and its single crystal was grown for light-emitting field effect transistors (FETs). This molecule forms J-aggregate crystals which show high luminescent efficiency compared with the corresponding H-aggregates. Although J-aggregates have a weak point of lower mobility, the FETs using trans-DPDSB single crystals and Au-Ca asymmetrical electrodes showed light emission from the channel. This study shows that the design and modification of organic molecular stacking modes are useful in realization of highly efficient light-emitting FETs.
