Abstract—

The spectral luminescent and electrophysical properties of polymer films based on poly-N-vinylpyrrolidone with the stabilized derivatives of tetraphenylporphyrin in various aggregation states (monomers, J- and H-aggregates) were investigated. Films containing a monomolecular form of porphyrins are characterized by intensive fluorescence. For films with J-aggregates an electric response that was not practically observed in the case of H-aggregates was detected. The films obtained are also characterized by optical and electric response to pH change, particularly in the presence of ammonia and hydrogen chloride vapors. The obtained data allow polymeric films with immobilized porphyrins to be considered as potential material for the creation of film systems for sensor applications, photovoltaics, molecular electronics, and photocatalysis. The variability of the film synthesis methodology allows the aggregation state of the immobilized porphyrins to be changed directionally, which provides the possibility of obtaining films of hybrid organic materials with the desired photophysical properties.

基于聚-N-乙烯基吡咯烷酮的聚合物膜中四苯基卟啉衍生物的聚集态

摘要-

基于聚氮的聚合物薄膜的光谱发光和电物理性质研究了具有各种聚集态（单体，J和H聚集体）的四苯基卟啉稳定衍生物的-乙烯基吡咯烷酮。包含卟啉单分子形式的薄膜的特征在于强烈的荧光。对于具有J聚集体的薄膜，检测到在H聚集体情况下实际上未观察到的电响应。得到的薄膜的特征还在于对pH变化的光学和电响应，特别是在存在氨和氯化氢蒸气的情况下。所获得的数据使得具有固定化卟啉的聚合物薄膜被认为是潜在的材料，可用于传感器应用，光伏，分子电子和光催化的薄膜系统的创建。
