CONTROL OF ASSOCIATED STATE OF ORGANIC DYE USING MAGNETIC FIELD

摘要

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.
