摘要: 合成了两种新型手性锌卟啉Zn(o-BocTyr)TAPP和Zn(p-BocTyr)TAPP.通过元素分析、紫外可见光谱及核磁共振谱对其性质进行了表征.研究了这两种锌卟啉对咪唑类的分子识别行为,识别的缔合常数顺序均为K(2-MeIm)>K(Im)>K(N-MeIm)>K(2-Et-4-MeIm).同时,采用理论计算和圆二色谱研究了咪唑类小分子在与锌卟啉分子识别时进攻主体位置的变化,这对于研究卟啉分子识别起到一定的作用.

Abstract: Two kinds of novel chiral Zn porphyrin complexes were synthesized and characteried by means of elementary analysis, UV-Vis, 1H NMR. Molecular recognition was studied between hosts and imidazole derivatives. Association constants of Zn(o-BocTyr)TAPP and Zn(p-BocTyr)TAPP with imidazoles increased in the sequence K(2-MeIm>K(Im)>K(N-MeIm)>K(2-Et-4-MeIm). Through circular dichroism spectra and theoretical calculation method, the chang of position in which imidazoles coordinated to host 1 was studied, it is important to study the structral characterization of porphyrin.

Key words: Chiral porphyrinatozine, Imidazole derivatives, Chiral molecular recognition, Circular dichroism spectra, Molecular mechanics
