Langmuir-Blodgett-Films of a Donor Substituted Bianthrone Derivative
The compound 3-(2,3-dimethyl-6-octadecyl-1,4-dithiafulven-6-yl)-bianthrone forms stable Langmuir films at a water/argon interface. Oxidative decoupling of the bianthrone - and dithiafulven halfs of the molecule occur at the interface in the presence of light and oxygen. Transfer to hydrophobe substrates by vertical dipping leads to Langmuir-Blodgett films of the Y-type. The fluorescence and the corresponding molecular charge transfer band, present in nonpolar solutions, are preserved when molecules go from solution to LB-films. The A- to B-form transformation of the bianthrone moiety could not be accomplished in the LB-films under experimental conditions similar to those which lead to the B-form in solution.
