Abstract: NEW MATERIAL:An electron acceptor shown by formula I (R is long-chain alkyl). EXAMPLE:Octadecyl tetracyanoquinodimethane. USE:An intermediate for synthesizing an electric charge transfer complex compound. The electron acceptor is reacted with an electron donor and a stable monomolecular layer is formed on the surface of water to give an electric charge transfer complex compound having improved electrical conductivity and stability. PREPARATION:A 2-ocatadecyl-1,4-bis(dicyanomethylene)cyclohexane shown by formula II is stirred with triethylamine and bromine in a solvent such as chloroform, etc., to give a compound shown by formula I. Tetrathiafulvalene is perferable as an electron donor to be combined with the electron donor and an electric charge transfer complex compound is shown by formula III.

Abstract: PURPOSE:To prompt the formation of J associated body and to transform a part of the area of thin film selectively to associate by controlling the associated state of org. dye molecules in Langmuir-Blodgett's film which is a typical example of org. ultra thin film by the impression of magnetic field. CONSTITUTION:A magnetic field is impressed to associated org. dye molecules in Langmuir-Blodgett's film which is a typical example of org. ultra thin film to prompt the formation of J associated body. An org. dye having the structure for forming the J associated body is used as the org. dye molecule. Suitable org. dye molecule is a molecule of cyanine dye, merocyanine dye, or squarylium dye. Further, the magnetic field to be impressed to the associated org. dye molecules is regulated to >=100 gauss. Thus, the formation of J associated body is prompted and selective transformation of a part of the area of thin film to associate has become possible.

Abstract: NEW MATERIAL:A charge-transfer complex having long-chain hydrocarbon group of formula I (R is long-chain alkyl). EXAMPLE:Octadecyl-tetracyanoquiondimethane-tetramethyltetracyano quinodimethane (1,1) complex. USE:An electron acceptor that gives charge-transfer complex which can form monomolecular layer stably on the water surface. PREPARATION:The reaction of 1,4-dimethoxybenzene of formula II with R-COCl gives a compound of formula III. The product is catalytically hydrogenated in the presence of a palladium-carbon catalyst into a compound of formula IV. Then, the compound is converted into compounds of formula V, VI and VII in order. Finally, the product is allowed to react with an electron donor, preferably tetramethylterathiafluvalene to give the objective charge transfer complex of formula I.
