本研究合成了兩個系列的高分子，一為使用非線性光學係數高的DR-19發色團與奈環合成聚酯高分子，另一則由DR-19與光架橋基團（cinnamylidenemalonic acid）的合成來進行光架橋。
研究結果顯示，含奈環的高分子系列有良好的加工性和成膜性，且該材料為非晶性，有良好的透光度。由於含奈環高分子的Tg不高，故以光架橋基團取代奈環，希望以架橋的形成來穩定分子鏈的移動，目前已完成架橋前的高分子性質，可為架橋高分子的延續基礎。
將上述三種高分子利用電暈極化（corona poling），使其發色團（chromophore）產生配向（orientation）形成不對稱中心，接著利用反射式電光係數檢測儀器來測量r33值，測得的值為1.75∼3.17 pm/V之間，所得之值是偏低，推測材料的表面需要蒸鍍法鍍上一層鋁膜，在此高溫的環境下，擾亂了發色團的配向，故也使電光系數值偏低，所以需要以其他儀器來測量，如測定d33才能確定真正的值。

In this research, two series of polymers were prepared. One polymer containing DR-19 as a nonlinear optically active chromophore with naphthalene group have been synthesized. The other polymer containing DR-19 with photo-cross-linkable group (cinnamylidenemalonic acid) have been syntheaized.
The results show that the polymer containing naphthalene group have good processibility and can be easily casting as thin film. Those polymers have no crystalline and exhibit good opacity. Because of the polymers containing naphthalene do not have high Tg, so we have used cinnamylidenemalonic acid instead of naphthalene group . In order to prevent rotation and translation of the chromophore molecules. , we have synthesized and characterized the polymer containing crosslinkable group.
In order to make the polymer consist of chromophores oriented. We used corona poling technique to form noncentrosymmetry. The electro-optical (EO) measurement was set up by a reflection method. The EO coefficient r33 range from 1.75~3.17pm/V was obtained after poling . The measurement were not expected values .Because of the thin film of NLO material deposited in vacuum. We supposed the high temperature environment disturbed the orientation of chromophores. It made the chromophores relaxation., and reduced the EO value.
