PREPARATION OF LANGMUIR-BLODGETT-FILMS CONTAINING A CHARGE-TRANSFER COMPLEX OF ALKYLATED DICYANOQUINONEDIIMINE (DCNQI) AND COPPER

An alkylated N,N'-dicyanoquinonediimine (alkylDCNQI) derivative has be en synthesized and the Langmuir-Blodgett (LB) technique has been appli ed to this material and its mixture with CuI, aiming at the constructi on of a DCNQI-Cu system in two dimensions. No chemical reaction could be detected for alkylDCNQI-CuI mixed solutions. However, optical measu rements have shown that the LB films obtained from the mixture contain a partially reduced DCNQI group, suggesting that a new CT complex is obtained by in situ reaction of alkylDCNQI and CuI at the air-water in terface.
