Aggregation and luminescent pro0perties of some oxadiazole derivatives incorporated in poly(methylmethacrylate) Langmuir-Blodgett ftilms

摘要

Characteristics of fluorescence have been studied for three oxadiaxzole derivatives (OXD) incoporated in Langmuir-Blodgett (LB) films mixed with poly(methylmetacrylate). As the OXD concentration increases, the monolayer structurization process becomes subdivided into two stages. At the first one, limited mixing of components in monolayeres occurs while at the second, the dopant is released as a spearate pahse of the monolayer.
