Synthesis, structural characterization, and luminescence properties of zinc(II) coordination polymers containing bis(4-pyridyl)benzylamine
Two new zinc(II) coordination polymers [Zn(bpba)2(NO3)2]n (1) and [Zn(bpba)(SO4)]n•2nH2O•nDMF (2) were successfully synthesized by reacting zinc(II) ions with bis(4-pyridyl)benzylamine (bpba) containing different counter anions (NO₃− and SO42−). The resulting polymers were fully characterized using various experimental techniques: single-crystal X-ray diffraction analysis, elemental analysis, infrared spectra, ultraviolet/visible spectra, and thermogravimetric analysis. Single-crystal X-ray analyses revealed that the zinc(II) ions in 1 and 2 are tetra-coordinated and adopt a distorted tetrahedral geometry. Polymer 1 exhibits a one-dimensional helical chain structure, which extends into two-dimensional supramolecular networks through hydrogen bonding and C-H•••π interactions. Polymer 2 adopts a three-dimensional network structure resulting from the coordination of zinc(II) and sulfate ions as well as bpba ligands. An investigation of the solid-state photoluminescence properties of the polymers at room temperature revealed that their emissions were redshifted compared with those of the free ligand, which is attributed to metal-perturbed intra-ligand charge transfer.
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.
