An investigation of the complexation behaviour of structurally modified tetrathiafulvalene derivatives with the electron deficient cyclophane cyclobis(paraquat-p-phenylene)

Abstract

This study has shown that easily oxidisable TTF units form charge-transfer (C-T) complexes with 7 which have the largest reported association constants to date. Replacing the sulfur of the TTF unit with selenium or extending the conjugated link between the two dithiole rings reduces the K-a of the complex relative to the parent derivative.
