The synthesis of alternating donor-acceptor [12] and [16]cycloparaphenylenes (CPPs) has been achieved by the rhodium-catalyzed intermolecular cross-cyclotrimerization followed by imidation and/or aromatization. These alternating donor-acceptor CPPs showed positive solvatofluorochromic properties and smaller HOMO-LUMO gaps compared with nonfunctionalized CPPs, which was confirmed by the theoretical study.
通过铑催化的分子间交叉环三聚反应，随后进行亚胺化和/或芳构化，实现了交替供体-受体[12]环对苯撑和[16]环对苯撑（CPPs）的合成。与未官能化的CPPs相比，这些交替供体-受体CPPs表现出正溶剂化氟致变色性质和更小的最高占据分子轨道-最低未占据分子轨道能隙，这一点通过理论研究得到了证实。
