我们提出了在高频电光应用中处理透明/光学非线性权衡的相关结果。非常简单，稳定和高光学间隙的发色团，两性离子1-甲基-4-（四唑-5-酸）吡啶，代表了迄今为止文献中描述的最佳透明度/光学非线性权衡。我们在键长交替理论的框架下，通过多学科的方法，包括：单晶x射线结构，电场诱导的二次谐波产生，溶剂变色，电化学和热分析，来证明这一卓越的性能。
We present relevant results dealing with the transparency/optical nonlinearity trade-off in high-frequency electro-optic applications. The very simple, stable and high optical gap chromophore, the zwitterion 1-methyl-4-(tetrazol-5-ate) pyridinium, represents the best transparency/optical nonlinearity trade-off so far described in the literature. We rationalize this remarkable performance in the framework of the Bond Length Alternation theory by means of a multidisciplinary approach including: single crystal X-ray structure, Electric Field Induced Second-Harmonic Generation, solvatochromism, electrochemistry and thermal analyses.
