Abstract
We report the synthesis and characterization of two new fluorophores, consisting of a [8]cyclo--phenylene core in which two phenylenes are bridged by either a nitrogen atom or a carbonyl group. The nitrogen bridge increases the HOMO-LUMO gap, whereas the carbonyl bridge decreases it. These results provide guidelines to control the electronic properties of nanohoops.
摘要
我们报道了两种新型荧光团的合成与表征，它们由一个[8]环亚苯基核心组成，其中两个亚苯基通过一个氮原子或一个羰基桥连。氮桥增加了最高已占分子轨道（HOMO）与最低未占分子轨道（LUMO）的能隙，而羰基桥则降低了该能隙。这些结果为控制纳米环的电子性质提供了指导方针。
