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。

carbonyl-aromatic (CO-π) interactions. Carbonyl oxygens were observed to form repulsive interactions with unsubstituted arenes and attractive interactions with electron-deficient arenes with multiple electron-withdrawing groups. The repulsive and attractive CO-π aromaticinteractions were well-correlated to electrostatic parameters, which allowed accurate predictions of the interaction energies based on the

9,10-Anthracenedicarboxaldehyde bis[(4,5-dihydro-1H-imidazol-2-yl)hydrazone] (bisantrene, VI-1) showed anticancer activity in mice vs. both leukemias and solid tumors. Increases in life span vs. the following neoplasms were: P-388 leukemia, 137%; B-16 melanoma, 122%; Lieberman plasma cell tumor, greater than 85%; colon tumor 26, 150%; Ridgway osteogenic sarcoma, 85%. There were significant numbers of long-term survivors. Both DNA and RNA synthesis were strongly inhibited. The drug was resistant to biodegradation and was bound strongly to tissues; in monkeys the half-life for disappearance from serum was 6 days. Related hydrazones were synthesized, and structure-activity relationships are discussed. Two routes to ring-substituted anthracene-9,10-dicarboxaldehyde intermediates were developed.

In designing organicsemiconductors for organic devices, halogenation is a very popular strategy for tuning the electronicproperties and packing arrangement in the solid state. Herein, we report the synthesis and characterization of halogenated dibenzo[a,j]perylene (DBP) with triethylsilyl (TES)-ethynyl substituents at the 8- and 16-positions (TES-DBP). The resulting compounds are characterized by
