Abstract

Herein, a series of four amide-bonded hydroxyquinoline-substituted porphyrins have been prepared and characterized. Trends in the electronic structures are investigated by spectroscopic and electrochemical analysis to explore the effect of the functional amide-bonded hydroxyquinoline units. Also, the selective pH sensing properties were also performed and their plausible mechanism were also proposed. And the proposed mechanisms is the photoinduced electron transfer mechanism.

期刊介绍： The Journal of Inclusion Phenomena and Macrocyclic Chemistry is the premier interdisciplinary publication reporting on original research into all aspects of host-guest systems. Examples of specific areas of interest are: the preparation and characterization of new hosts and new host-guest systems, especially those involving macrocyclic ligands; crystallographic, spectroscopic, thermodynamic and theoretical studies; applications in chromatography and inclusion polymerization; enzyme modelling; molecular recognition and catalysis by inclusion compounds; intercalates in biological and non-biological systems, cyclodextrin complexes and their applications in the agriculture, flavoring, food and pharmaceutical industries; synthesis, characterization and applications of zeolites. The journal publishes primarily reports of original research and preliminary communications, provided the latter represent a significant advance in the understanding of inclusion science. Critical reviews dealing with recent advances in the field are a periodic feature of the journal.
