This review is aimed at the current research progression of a unique class of Pt(II) metal complexes bearing at least one azolate-containing bidentate chelate. The azole fragment can link to a neutral heteroaromatic entity or another azole and form bidentate chelates, such as monoanionic 3-pyridyl-1H-pyrazole and derivatives, dianionic 3,3′-bi-1H-pyrazole, 3,3′-(1-methylethylidene)-bis-1H-pyrazole, and their analogs. These azole-containing chelates readily react with a variety of Pt(II) reagents to afford the corresponding bis-bidentate Pt(II) complexes. Most of them were highly emissive in solution, doped polymer matrix, thin film, and even as crystal or powder, due to the high ligand field strength exerted by these chelates and their high propensity in forming the singular square-planar architecture and intermolecular aggregates with substantially strengthened Pt⋯Pt interaction, according to their structural design. Therefore, they hold bright prospects in academic research and future optoelectronic applications such as organic light-emitting diodes.
