摘要

本文乃是介紹有機材料的三次非線性光學性質。文中著重於分子結構的改變如π-電子delo-calization、雜原子、電子施體受體強度、結構次元、取向、構形、平面度、及anharmonicity對三次非線性光學性質的影響。所探討的材料則涵蓋不同類型的共軛分子及高分子。簡單的理論模型essentialstates mechanism將被使用來解釋共軛高分子的χ^((3)) (-3ω;ω,ω,ω)光譜。

並列摘要

In this article, the third-order nonlinear optical properties of organic materials are described. The effects of the structural changes such as π-electron delocalization, heteroatorm, electron donors and acceptors, dimension, orientation, conformation and anharmonicity on the third-order nonlinear optical properties of molecules and polymers are discussed. Essential states mechanism is used to interpret the χ^((3)) (-3ω;ω,ω,ω) spectra of conjugated polymers.
