Structures based on cyclophanes continue to arouse interest because of their unique physical properties, and their ability to act as model compounds for the study of intramolecular processes 1. and 2. and host–guest chemistry. 3 Cyclophanes containing extended π-conjugation have been investigated as mimics for solid-state interactions involving photoexcitation 4 and for electron transfer processes involving extended orthogonal π-systems. 5 The classical, and still ...
