Fig. 1. Schematic representation of the functionalization of a cross-shaped molecule with chromophores to obtain a library of mono- or hybrid chromophores. (a) Cross-shaped motif consisting of both (M) and (P) conformers adopting a distorted tetrahedron conformation. (b) Target chromophores for functionalization. (c) Library of decorated cross-shaped tetrachromophores. (d) A hybrid chromophore showing intramolecular-FRET activity, which after template cleavage results in the liberation of two differently decorated rigid rods.
