设计并合成了一种新型偶氮苯类光致变色非晶态分子材料三[4-（苯基偶氮）苯基]胺（TPAPA）。发现TPAPA容易形成玻璃化转变温度为67 ℃的非晶玻璃，并且作为非晶膜显示光致变色性。用两束相干Ar ~+激光辐照TPAPA非晶薄膜，形成了衍射效率约为2 ~ 3%，调制深度约为10 μ m的表面浮雕光栅。100 nm。
A novel azobenzene-based photochromic amorphous molecular material, tris[4-(phenylazo)phenyl]amine (TPAPA), was designed and synthesized. TPAPA was found to readily form an amorphous glass with a glass-transition temperature of 67 degrees C and to exhibit photochromism as amorphous film. Irradiation of amorphous film of TPAPA with two coherent Ar+ laser beams led to the formation of surface relief grating with a diffraction efficiency of 2 similar to 3% and a modulation depth of ca. 100 nm.
