Abstract: The dyes with donor-π-conjugated bridge acceptor(D-π-A) structure exhibit a good photoelectric conversion property and excellent second order nonlinearity because they can cause photoinduced intramolecular electron transfer along-π-conjugated bridge. In the same time, the dyes receiving a suitable molecular modification also exhibit an electron conductivity and ion selectivity. The latest advances of multifunctional LBfilm of D-π-Adye systems were reviewed in this paper. The applications about LBfilm of D-π-Adye systems in second order nonlinear optics, photoelectric conversion and conductivity, etc. were specially discussed here.

Key words: Multifunctional properties, D-π-A dyes, LB film
