Abstract
Electron-tranfer of the excited carbazole chromophore in poly(N-dodecylacrylamide-co-N-vinylcarbazole)s (DDA/Cz) polymer monolayers by three different N-stearyl para-substituted pyridinium derivatives (X-Py) (p-COCH 3 , p-COOCH 3 , and p-CONH 2 ) has been investigated in Langmuir-Blodgett (LB) assembly systems by using a steady-state emission quenching method. Three different mixed monolayers of the pyridiniums with stearic acid (St) are in direct contact with the DDA/Cz monolayers having various Cz contents to investigate the influence of the redoc potentials of the quenchers and the effect of energy migration between the Cz chromophores on the electron-transfer quenching in the LB films
