Abstract
Axially chiral binaphthalene chromophores (BN) can be incorporated into polymer Langmuir-Blodgett (LB) films as comonomers of N-alkylacrylamides which have an excellent ability to form stable monolayers and LB multilayers. The spreading behavior of the copolymers of (S)-2-methoxy-1,1'-binaphthalen-2'-yl methacrylate ((S)-MeBN) or (S)-2-hydroxy-1,1'-binaphthalen-2'-yl methacrylate ((S)-HOBM) with N-decyl-(DA), dodecyl-(DDA), or tetradecylacrylamide (TDA) was investigated by a measurement of the surface pressure-area isotherms. The isotherms show that the copolymers, especially DDA copolymers, form a stable condensed monolayer on pure water and the axially chiral binaphthalene chromophore is dispersed uniformly, having its own surface area on water when the mole fraction of BN is less than ca. 20 mol%
