New dipolar conjugated dendrons with electron-withdrawing groups on the periphery and electron-donating groups distributed at the core and throughout the dendritic skeleton have been conveniently synthesized. The pi-conjugated dendritic skeleton provides extended conjugation between each electron donor-acceptor pair, resulting in numerous traditional nonlinear optically active chromophores in one single
方便地合成了新的偶极共轭树枝状分子,该树枝状分子的外围有吸电子基团,而供电子基团分布在核心和整个树枝状骨架上。π共轭的树枝状骨架在每个电子供体-受体对之间提供了扩展的共轭,从而在一个单一的树枝状结构中产生了许多传统的非线性光学活性发色团。
