通过水相亚相中引入的聚电解质在空气-水界面处络合半花青基两亲物被证明是一种方便有效的途径，可以实现 Langmuir-Blodgett (LB) 膜中染料发色团的完全解聚，而不降低二维晶格中的发色团密度。证明了半花青聚电解质的 LB 膜增强了光学二次谐波的产生。
Complexation of a hemicyanine-based amphiphile at the air−water interface by polyelectrolytes introduced in the aqueous subphase is shown to be a convenient and effective route to achieve complete deaggregation of the dye chromophores in the Langmuir−Blodgett (LB) film without reducing the chromophore density in the two-dimensional lattice. Enhanced optical second harmonic generation from the LB films of the hemicyanine−polyelectrolyte is demonstrated.
