聚喹啉/十八酸/过渡金属取代杂多阴离子杂化LB膜的制备及性质研究

Fabrication and Characterization of Hybrid Organic/Inorganic Langmuir-Blodgett Films of Polyquinoline/Stearic Acid/ Transition Metal-substituted Heteropolyanion

将聚喹啉(PQ)、十八酸(SA)和过渡金属取代的杂多阴离子PW11ZO40n-(Z=CuII,CoII,MnII,NiII)通过LB技术掺杂,成功地制备了四种PQ/SA/杂多阴离子杂化LB膜,通过π-A曲线、荧光、吸收光谱、原子力显微镜等手段对PQ/SA/杂多阴离子杂化LB膜的成膜方式、性能、结构及形貌进行了表征.原子力显微镜研究表明,沉积在LB膜表面的杂多化合物颗粒大小在55～70nm之间.

Four kinds of hybrid organic/inorganic Langmuir-Blodgett films are obtained by the compact organization of poly(1,2-dihydro-2,2,4-trimethyl)quinoline (briefed as PQ), stearic acid (briefed as SA) and transition metal-substituted heteropolyanions (briefed as PW_(11)Z, Z=Cu^(II),Co^(II),Mn^(II),Ni^(II))using the Langmuir-Blodgett technique. They are characterized by the π-A isotherms, the absorption spectra, the fluorescence spectra and the atomic force microscope. The atomic force microscope revealed a granular surface texture of nanosized transition metal-substituted heteropolyanions ranging from 55 to 70 nm.
