Organic semiconductors integrating excellent charge transport with efficient solid emission are very challenging to be attained in the construction of light-emitting transistors and even for realization of electrically pumped organic lasers. Herein, we introduce naphthyl units at 2,6-positions of anthracene to achieve 2,6-di(2-naphthyl)anthracene (dNaAnt), which adopts J-aggregated mode in the solid state as a balanced strategy for excellent charge transporting and efficient solid state emission. Single crystal field-effect transistors show mobility up to 12.3 cm2·V–1·s–1 and a photoluminescence quantum yield of 29.2% was obtained for dNaAnt crystals. Furthermore, organic light-emitting transistors (OLETs) based on dNaAnt single crystals distribute outstanding balanced ambipolar charge transporting property (μh = 1.10 cm2·V–1·s–1, μe = 0.87 cm2·V–1·s–1) and spatially controllable emission, which is one of the best performances for OLETs.

蒽在2,6-位上的芳香扩展，是一种具有高效电荷传输和强固态发射的有机半导体优雅策略
在发光晶体管的构造中甚至对于实现电泵浦有机激光器而言，要实现将优异的电荷传输与有效的固体发射相结合的有机半导体是非常具有挑战性的。在这里，我们在蒽的2,6-位引入萘基单元，以实现2,6-二（2-萘基）蒽（dNaAnt），其采用固态的J聚集模式作为平衡策略，以实现出色的电荷传输和高效固态发射。单晶场效应晶体管的迁移率高达12.3 cm 2 ·V –1 ·s –1dNaAnt晶体的光致发光量子产率为29.2％。此外，基于dNaAnt有机发光晶体管（OLETs）单晶分发优秀均衡双极性电荷输送性（μ ħ =1.10厘米2 ·V -1 ·S -1，μ Ë =0.87厘米2个·V -1 ·s的–1）和空间可控的发射，这是OLET的最佳性能之一。
