摘要
通过紫外-可见吸收光谱、压力-面积等温线、二次谐波的测量,研究了不同活性分子混合聚集体的形成对LB膜光学性质的影响。分子极性基团间的相互作用,使激发态能量及平均偶极矩发生变化,导致LB膜的光学非线性明显地增强或减弱。
Abstract
Effects of the mixed aggregates of different active materials on optical properties of LB films have been investigated by UV-visible absorption, π-A isotherm and second harmonic generation (SHG) measurements. The chromophore interactions change the optical nonlinearity of LB films via variations in the excited state energy and average electric dipole moment of molecules.
