基于二氢[1,2-供体/受体半导体的新家族一]芴和二氢[2,1- b ]芴报告。由于螺旋桥的作用,新一代的二氢茚并芴可实现HOMO和LUMO的空间分离,从而保留了二氢茚并芴骨架的高E T值和出色的物理性能。对电子和物理性质的这种控制使第二代二氢茚并[1,2- a相对于第一代材料,在绿色和天蓝色磷光有机发光二极管(PhOLED)中可获得性能大大增强的]芴。迄今为止,这是使用二氢茚并芴衍生物对蓝色PhOLED进行报道的最高性能。通过这种结构-性质关系研究,还强调了顺式异构体和反式异构体之间的显着差异。这种令人惊讶的行为归因于两个分子的不同对称性,并突出了几何轮廓在PhOLED主体材料设计中的重要性。

An enantioselective palladium-catalyzed annulation of alkyne-tethered malononitriles for the synthesis of 3,4-ring-fused isocoumarins is described. This cascade strategy involves oxypalladation of ortho-alkynylbenzoates and desymmetrizing addition onto one cyano group of the pendant malononitriles, which enables the concurrent construction of two rings and an all-carbon quaternary stereocenter in a

strategy of one-pot synthesis of protoberberine alkaloid derivativesvia palladium-catalyzed cascade α-arylation and cyclization, which can afford the target molecules in moderate to excellent isolated yields using commercially available raw materials under solvent-free conditions. This protocol provides an efficient and convenient path to multisubstituted protoberberine derivatives. In addition, it can
