通过交替吸附纳米级的WO3胶体粒子和3种分别含1个,3个和6个亚甲基碳链的双偶极半菁制备了新颖的无机-有机杂化自组装多层膜,并通过紫外-可见光谱和光电化学对薄膜进行了研究.结果表明这种WO3/半菁静电自组装多层膜可被均匀沉积,与文献报道的半菁分子Langmuir-Blodgett膜相比,具有制备简单、红移的可见吸收峰和含3个亚甲基碳链的双偶极半菁光电信号强的优点.
Novel inorganic-organic hybrid self-assembled multilayer films were prepared by alternately adsorbing nano-sized WO3 colloidal particles and three double dipolar semicarbocyanines containing 1, 3, and 6 methylene carbon chains, respectively, UV-Vis and photoelectrochemistry.The results show that the WO3 / semicalen electrostatic self-assembly multilayer films can be uniformly deposited, compared with the Langmuir-Blodgett film reported in the literature, it has the advantages of simple preparation, The red shift of the visible absorption peak and three methylene carbon chain double dipolar semi-cyanine photoelectric signal advantages.
