Fluorescence quenching could be ascribed to an electron transfer mechanism, rather than to an energy frunsfer process, on the basis of spectrofluorimetric investigations carried out at 77K (which showed a sharp revival of anthracene fluorescence).

18. Lehn’s redox switchable system (4) does not fit any combination in Table I, as the oxidized and reduced states are separated by two electrons. However, it belongs to the same class of system (5), in the sense that the oxidized form of the control unit quenches fluorescence, the reduced one does not. For a complete treatment of thermodynamic and kinetic aspects of the photochemical behaviour of (4) see also reference 19.

20. The work term of the Rhem-Weller equation, 21 which takes into account the favourable electrostatic contribution for the formation of the charge-transfer excited state, has been considered negligible to a first approximation and has been omitted in the equations in Table I.

23. Carotenoid-type conjugated hydrocarbon chains have been used to separate donor and acceptor in photoinduced electron-transfer studies on molecular triad. Lehn has considered the use of similar conjugated polyolefinic chains to transport electrons between terminal equivalent or non-equivalent redox active subunits.
