Notes:
Experimental IR properties of conducting (ODS-TCNQ)ξ(TCNQC18)1−ξ Langmuir–Blodgett (LB) films are presented and discussed within the frame of the electron-vibration coupling model of Rice, extended to take into account the modifications induced by grafting an alkyl chain to the TCNQ molecule. The quite good theoretical fit of experimental spectra (including unusual fine structure of agν5 vibronic band) indicates that (i) optical as well as electrical properties of the films can be accounted for by the existence of dimers the type of which depends on ξ; and (ii) inside the layer, an energy transfer takes place between the electroactive part and the alkyl chain via a two step coupling process.
