| 摘 要： | 通过对杯芳烃-卟啉化合物及其锌、钯配合物LB膜的表面压-表面积等温线、紫外可见光谱和傅里叶变换红外光谱的检测,研究了它们在气/液界面和Langmuir-Blodgett膜中的性质,并用量子力学方法优化了杯芳烃-卟啉化合物的构型.结果表明,成膜时3种化合物分子中卟啉环都倾斜地排列在亚相表面,且卟啉环间存在π-π相互作用.连接杯芳烃和卟啉之间的碳氢链在膜性质中起着重要的作用,杯芳烃-卟啉化合物分子中这种碳氢链的有序性小于其锌、钯配合物分子中的这种碳氢链有序性.

| Abstract: | The behavior of calixarene-porphyrin compound and its zinc,palladium complexes are studied in Langmuir-Blodgett films by measuring their pressure-area isotherm,ultraviolet-visible and fourier transform infrared spectroscopy.The molecular geometry of the calixarene-porphyrin compound is optimized with quantum chemistry method.The results indicate that all molecules are packed with tilted porphyrin rings with respect to the aqueous subphase when films formed in three compounds.The hydrocarbon chain between ca... |
