摘要:

J-aggregation of cyanine molecules was induced in two types of mixed LB films by the photoisomerization of azobenzene coexisting in the same LB films. Drastic morphological changes involving the formation of three-dimensional cone-shaped structures protruding from the film surfaces were observed accompanied with the J-aggregation. This means that the two-dimensional LB film structures exerted substantial modification by the photoisomerization.
