Alkynylplatinum(II) terpyridine complexes have been increasingly explored since the previous decades, mainly arising from their intriguing photophysical properties and aggregation affinities associated with their extensive Pt(II)···Pt(II) and π–π stacking interactions. Through molecular engineering, one can modulate their fundamental properties and assembly behavior by introduction of various functional groups and structural features. They can therefore serve as ideal candidates to construct metal complex-based molecular architectures to provide an alternative to organic compounds. The metal-based framework can be simultaneously built from predetermined building blocks, giving rise to their well-defined, unique, and discrete natures for molecular recognition. The individual constituents can contribute to molecular architectures with their integrated properties, allowing the manipulation of the various noncovalent intermolecular forces and interactions for selective guest capture. In this Account, our recent progress in the development of these metallomolecular frameworks based on the alkynylplatinum(II) terpyridine system and their recognition properties toward different guest molecules will be presented.
