The tetrabenzo[ab,f,jk,o][18]annulenes 7a,b, generated in a 5-step synthesis, show photodimerisation and -oligomerisation reactions in the solid state and in solution. The state of aggregation determines the reaction route. Whereas the cyclodimer 8a has a simple cyclobutane structure, the dimer 8b is a highly symmetrical cyclophane.
在5步合成中生成的四苯并[ ab,f,jk,o ] [18]环戊烯7a,b在固态和溶液中显示出光二聚和低聚反应。聚集状态决定了反应路线。环二聚体8a具有简单的环丁烷结构,而二聚体8b是高度对称的环烷。
