含染料環氧樹脂之二階非線性光學性質

Abstract

本研究以含不同取代基的苯胺(aniline)與N,N-雙環氧苯胺(N,N- diglycidylaniline)利用重氮化反應，得到三種含環氧基的偶氮染料分子 ，分別為4-diglycidylamino-4'-nitroazobenzene、4-diglycidylamino -2'-chloro-4'-nitroazobenzene、4-diglycidylamino-2'-methyl-4'- nitroazobenzene。測量三者的基態偶極矩，且由EFISH method測量分子 的一階超極化度。以等當量比與硬化劑4,4'-methylenedianiline形成熱 固型非線性光學高分子材料，以薄膜干涉法求得532nm及1064nm時的折射 率，在 4kV電場極化下完成後硬化反應，以Maker fringe method測量材 料的二階非線性光學係數。 Reaction of aniline containing different substitutents and N,N- diglycidylaniline gave three azodyes.A first hyperpolariza- bility of the dyes in 1,4-dioxane were determined by EFISH method.4,4-methylenedianiline was used as a curing agent for the diglycidyl dye molecules.The second-order nonlinear coefficient were obtained by Maker fringe method.
