Molecular arrangement and thermal reorganization of merocyanine J‐aggregate monolayers on solid substrates

Amphiphilic merocyanine dyes form J‐aggregates at the air–water interface. For any application the thermal behavior of the monolayers in an important issue and hermally induced phase transitions in monolayers have been intensively studied. Langmuir–Blodgett monolayers of two merocyanine dyes mixed with matrix molecules (see figure) have been examined and the optimization of the thermal stability of such systems discussed. magnified image
