High Reactivity of Heterocoerdianthrones (HCDs) in Photoperoxidation and Thermal Stability of Their Endoperoxides. Use of HCD as a Photosensitizer under Sunlight
在设计用于有机器件的有机半导体时,卤化是调节固态电子特性和排列方式的一种非常流行的策略。本文中,我们报道了卤代二苯并[ a,j在8和16位带有三乙基甲硅烷基(TES)-乙炔基取代基的](DBP)(TES-DBP)。通过光学,电化学,晶体学和计算研究对所得化合物进行表征,以阐明卤化对光电性质和电荷载流子传输的影响。发现卤素原子,卤化程度及其位置可以改变化合物的电子性质和晶体堆积。与氟化TES-DBP相比,由于DBP核与Cl原子的未占据3d轨道之间的电子离域,氯化对应物具有最大的红移和较低的电子亲和力。有机场效应晶体管的测量表明TES-2ClDBP的空穴迁移率为0.25 cm 2 V–1 s –1,它高于TES-2FDBP和TES-DBP。另一方面,TES-4ClDBP具有双极性传输特性,电子和空穴迁移率分别高达0.02和0.07 cm 2 V –1 s –1。

Highly unusual properties of acene-based quinones 1A and 1T are reported. They undergo an unexpected combination of Michael and carbonyl additions of aryllithium leading to new triarylated benzoperylenes 3A and 3T. Uncharacteristically for quinones, 1A and 1T display vibronically split absorption bands and small Stokes shifts. The absorption/emission spectra of the highly emissive 1A are almost indistinguishable
An improved method for the synthesis of the title compound 1 has been achieved through an application of the Scholl reaction. The key to the new approach is to use the dimeric compounds of 10-methyleneanthrone as the precursors of 1.
