摘要
反-1,2-双[2′-(5′-苯基恶唑基)]乙烯(POEOP)系列化合物是一类紫外吸收波长处于可见光区的新型激光染料,还可用作闪烁剂,激光活化底物。
The crystal structure of the title compound has been determined by X-ray diffrac-tion method. The crystal is monoclinic, space group P 2_1/c with a=0.8268(2). b=0.5977(2). c=1.6292(3)nm, β=100.55(2)°, V=0.7915nm^3. Z=2, D_x=1.319g/cm^3. The mole-cule is centrosymmetric, its two benzene and two oxazole rings are coplanar but they aretwisted slightly to form a propeller-shaped molecule. Tbe bond distances indicate that thereis appreciable conjugation between vinyl and oxazole ring as well as oxazole end benzenerings.
