Abstract

A new anthraquinone-based tetra-benzimidazolium salt 1,8-bis{2’-[2’’-(N-picoly-benzimidazoliumyl)ethyl]benzimidazoliumyl}ethoxy-9,10-anthraquinone hexafluorophosphate (1) was prepared and characterized. Particularly, the recognition performance of H₂PO₄⁻ using of compound 1 as a chemical sensor was investigated through fluorescence spectra, ultraviolet spectra, HRMS, ¹H NMR titrations and IR spectra. The experimental results showed compound 1 has a good recognition ability for H₂PO₄⁻.

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.
