含咔唑与偶氮分散红共聚物的表面增强共振拉曼光谱研究

借助于表面增强共振拉曼光谱散射(SERRS)技术，研究了一种新型的偶氮聚合物材料侧链含咔唑与偶氮分散红共聚物(CAP)在化学沉积法制备的银膜表面的拉曼峰增强和吸附行为。实验结果显示，CAP在银表面的状态为: 聚合物通过咔唑单体中咔唑基团和偶氮单体中硝基与银膜衬底发生物理吸附，而聚合物的主链与衬底相距较远没有相互作用。可以推测，聚合物在衬底表面的这种状态将对偶氮光存储器件的稳定性和工作效率产生不良影响。

Surface Enhanced Raman Scattering Spectra of Carbozole and Azobenzene Disperse Red Polymer

Surface enhanced resonance Raman scattering(SERRS) was employed to study the molecule alignment of carbozole and azobenzene disperse red polymer on the surface of rough silver thin film.According to the selection rule of optical transitions and experiment results,it was found that the surface geometry of carbozole and azobenzene disperse red polymer was: this was physical adsorption between the carbazole group,which is from the monomer of carbazole and nitro-group which is from the monomer of azobenzene on the surface of rough silver film,and there is almost no interaction between the principal chain and the substrate because of the distance.This geometrical configuration of CAP on the surface of the substrate was proposed to damage the stabilities and efficiency of azobenzene derivatives based optical storage devices.
