Molecular materials that are both emissive and semiconducting are highly demanding for organic optoelectronics. In this article, we report the synthesis, emissive, and semiconducting properties of 1,6 and 2,7-trans-β-styryl substituted pyrenes (16PyE and 27PyE). The results reveal that both 16PyE and 27PyE are emissive and semiconducting in the solid state. The fluorescence quantum yields of crystalline
既具有发射性又具有半导体性的分子材料对有机光电子器件提出了很高的要求。在本文中,我们报告了1,6和2,7-反式-β-
苯乙烯基取代的((16PyE和27PyE)的合成,发射和半导体性质。结果表明,16PyE和27PyE在固态时都是发射性和半导电性的。测定出16PyE和27PyE的结晶固体的荧光量子产率分别为28.8%和27.4%。的
金属微16PyE和微孔板27PyE被发现表现出有希望的光波导行为。此外,根据各个有机场效应晶体管(OFET)的传输和输出曲线,发现16PyE和27PyE薄膜显示出p型半导体特性,空穴迁移率高达1.66 cm 2 V –1 s – 1。16PyE和27PyE的这种双重功能(发射性和半导体性)可以归因于16PyE和27PyE晶体内独特的分子间相互作用和堆积。1,6和2,7-反式-β-
苯乙烯基取代的pyr在固态下表现出较强的发射,并且它们的微晶样品表现出有希望的光波导行
