Bio-inspired cyclopeptidic heterodimers built on beta-sheet-like hydrogen-bonding networks and bearing photoactive and electroactive chromophores on the outer surface have been prepared. Different cross-strand pairwise relationships between the side chains of the cyclic alpha,gamma-peptides afford the heterodimers as three nonequivalent dimeric species. Steady-state and time-resolved spectroscopies clearly show an electron transfer process from pi-extended tetrathiafulvalene, covalently attached ...[more]
