Synthesis and properties of carbazole-terephthalate cyclophane
As a first example of carbazole-acceptor cyclophane, carbazole-terephthalate cyclophane 1a was prepared. The structure of 1a was characterized by H-1 NMR and X-ray analysis. Absorption spectrum of 1a showed the existence of transannular pi-pi electronic interaction and little charge transfer interaction. Fluorescence spectrum of 1a in THF exhibited intramolecular exciplex emission around 525 nm.
