One-dimensional coordination polymers based on metal–nitrogen linkages

In the past decades, one-dimensional coordination polymers (1D CPs) have been comprehensively studied on account of their unique architectures, fascinating properties, and versatile applications. The structures and properties of 1D CPs are determined by many factors, of which the ligand is the most crucial. In this review, we focus on N-donor ligand-based 1D CPs developed since 2015, including their chemical compositions, synthesis methodologies, topological structures, and structure–property relationships. Moreover, we classify N-donor ligands according to N-donor functional groups, including pyridine, imidazole, pyrazole, triazole, tetrazole, pyrimidine, pyrazine, amino, Schiff base, pyrrole, terpyridine, phenanthroline, dipyrrin, and azide. Finally, the challenges and outlook of N-donor ligand-based 1D CPs are rational discussed.
