A plethora of optical probes based on charge-transfer (CT) is known. Evidently such probes must contain at least one moiety with electron donor properties (D) and at least one with electron acceptor properties (A). While in some cases intermolecular D/A complexes have been employed, in general D and A are either linked directly or via a conjugated pi-system (D-π-A). However, in this chapter the focus will be on some fluorescent probes in which D and A are linked by an extended sigma-system (D-σ-A) that prevents direct D/A contact but still allows electronic interaction via a through-bond mechanism.
