Abstract

A novel stilbazolium salt with flexible chains, trans-[4-[N, N-bis (2-(2-methoxyethoxy) ethyl) amino] styryl]-N-methylpyridinium tetraphenylborate, was designed, synthesized and fully characterized. Third-order nonlinear optical properties for the new stilbazolium salt have been explored. The results show that the novel dye possesses very large values of the real part of the cubic hyperpolarizability χ (3), up to 10− 12 esu, and displays maximum two- ...
