Abstract
The tetrabenzo[ab,f,jk,o][18]annulenes 7a,b, generated in a 5-step synthesi s, show photodimerisation and -oligomerisation reactions in the solid state and in solution. The state of aggregation determines the reaction route. W hereas the cyclodimer 8a has a simple cyclobutane structure, the dimer 8b i s a highly symmetrical cyclophane. (C) 1999 Elsevier Science Ltd.
