Abstract

Abstract: A new single-chain amphiphile 1-hydroxyl-5-dodecyloxy-naphthalene can be deposited onto substr ates to form LB films by means of the L ang muir-Blodgett technique with pure ater as the subphase.The steady-state fluorescence spectra of the LB films were recorded.The dependence of the relative content of the naphthalene excimers in the films uponag gregation state indicates that the excimer for mation is promoted by increasing the close packing density of the molecules.The molecular orientation in the LB films was studied by fluor escence polarization technique,and the results revealed that the naphthalene chromophores or iented perpendicularly to the layer plane.
