Structrue of 1 hydroxy1 5 hexadecyloxy Naphthalene LB Films Studied by Fluorescence Spectroscopy

Abstract A new single chain amphiphile 1 hydroxy1 5 dodecyloxy naphthlene can be deposited as LB films onto substrates by using the Langmuir Blodgett technique with the subphase of pure water.Steady state fluorescence spectra of the LB films were recorded. The investigations on the dependence of the relative content of naphthalene excimers in the films upon aggregation state indicate that the excimer formation is promoted with increasing the close packing density of the molecules.
