一种卟啉-螺吡喃化合物的合成及其离子响应行为研究

合成了一种卟啉-螺吡喃化合物,并对其结构进行详细表征。在此基础上,通过紫外光谱研究了其光致异构与离子响应特征,并提出了一种解释卟啉环与螺吡喃之间耦合行为的新机制。研究结果表明,金属离子会诱导合成的卟啉-螺吡喃分子产生新的构象,从而影响螺吡喃的光致异构。此外,随着离子半径以及亲电能力的不同,卟啉-螺吡喃衍生物的光学特性也产生明显差异。这种卟啉-螺吡喃化合物为构建新型离子探针提供了一种思路。

Synthesis of a Prophyrin-Spiropyrane Compound and Its Ionic Response Behavior

A kind of porphyrin-spiropyrane derivative was synthesized and detailedly characterized.On this basis,the photoisomerization and ionic response behaviors of the compound were studied by UV-Vis spectrometry,and a new mechanism to explain the coupling behavior between porphyrin ring and spiropyrane was proposed.The experiental results showed that metal ions could induce porphyrin-spiropyran molecule to generate a new conformation which will affect the photoisomerization properties of spiropyrane.In addition,with the changes of ionic radius and electrophilic ability,the optical properties of the porphyrin-spiropyrane derivative presented significant differences.This study provides an idea for constructing a new ionic probe.
