Abstract :
The charge transfer properties of alkylTCNQ derivatives in the LB films of molecular conductors were examined. TMTTF, OMTTF and BEDOTTF were adopted as donors to form charge transfer complexes with C10 TCNQ or C14TCNQ. The degree of charge transfer of the alkylTCNQ in the LB films could be controlled from nearly neutral to fully ionic state by adopting appropriate donors for the counterpart. OMTTF-C10TCNQ formed a neutral complex which is located near the neutral-ionic boundary and is expected to be a candidate to realise neutral-ionic phase transition in the LB films.
