2,2 ',5',2 "-四溴-对-三联苯的四锂化反应和双硅环化反应生成双硅桥连的对-三联苯。在此基础上,合成了一系列新的梯型对三联苯衍生物。描述了它们的晶体结构和物理性质。
The tetralithiation reaction of 2,2',5',2' '-tetrabromo-p-terphenyl followed by a double silacyclization produces bis-silicon-bridged p-terphenyls. On the basis of this convenient method, a series of new ladder-type p-terphenyl derivatives have been synthesized. Their crystal structures and photophysical properties are described.
