Appropriate functionalization of the cyclometalated ligand, L, and the choice of the ancillary ligand, X, allows the dipolar second‐order nonlinear optical response of luminescent [PtLX] complexes—in which L is an N^C^N‐coordinated 1,3‐di(2‐pyridyl)benzene ligand and X is a monodentate halide or acetylide ligand—to be controlled. The complementary use of electric‐field‐induced second‐harmonic (EFISH)
适当地官能化环金属化配体L以及选择辅助配体X,可以实现发光[Pt L X]配合物的偶极二阶非线性光学响应,其中L是N ^ C ^ N配位的1 ,3-二(2-吡啶基)苯配体,X是要控制的单齿卤化物或乙炔化物配体。电场诱导的二次谐波(EFISH)生成和谐波光散射(HLS)测量的互补使用证明了这种吸引人的多功能生色团家族的二次超极化性是如何在整个可见区域中具有良好的透明度的。以八极贡献为主导。
