摘要

作为我们对金属-卟啉络合物(Colloids Surf)聚集研究的后续。答:Physicochem。Eng。Asp. 2022, 648, 129284),我们考虑在热衬底上沉积三种铜(II)乙卟啉异构体的薄膜。尽管同分异构体的吸收光谱几乎相同,但它们的固态超结构在形状和大小上都有显著差异。无论衬底温度如何,薄膜的横向电导率对异构体类型的敏感性要低得多。然而,冷生长薄膜的暗电导率比热生长薄膜高约两个数量级,而后者的光电导率则是100-1700倍,取决于异构体。

Aggregation and Conductivity in Hot-Grown Petroporphyrin Films
As a follow-up to our study on aggregation of metal-etioporphyrin complexes (Colloids Surf. A. Physicochem. Eng. Asp. 2022, 648, 129284), we considered thin films of three isomers of copper(II) etioporphyrin deposited on hot substrates. Despite the almost identical absorption spectra of isomers, their solid-state superstructures differ remarkably both in form and size. The lateral conductivity of films is much less sensitive to an isomer-type, regardless of the substrate temperature. However, the dark conductivity of cold-grown films is about two orders of magnitude higher than that of hot-grown films, whereas the photoconductivity of the latter is 100–1700 times greater, depending on the isomer.
