Abstract : Described is an approach to orthogonallyfused conjugated organic compounds that may act as molecular switching devices. Four thiophene trimers are added in a single operation to spiro-fused cores to afford the target molecules. A spiro-fused thiophene-based monomer system is converted to a spiro- fused heptamer that is 25 A long. The synthesis of a mixed phenylene-thiophene system is described
摘要:描述了一种可用作分子开关器件的正交稠合共轭有机化合物的方法。在一次操作中将四个噻吩三聚体添加到螺旋融合核心以提供目标分子。一个基于螺环稠合噻吩的单体系统被转化为一个长度为 25 A 的螺环稠合七聚体。描述了混合亚苯基-噻吩系统的合成,该系统提供了 30 长的螺合八聚体。在每种情况下,噻吩上的烷基取代基都提供可溶性物质。三甲基甲硅烷基端基位于每个正交稠合系统的侧翼。有机钯和有机镍催化的过程广泛用于合成正交稠合化合物。
