A series of newly designed and synthesized diacetylene‐containing platinum(II) terpyridine complexes exhibited intriguing self‐assembly properties. Facilitated by Pt ⋅⋅⋅ Pt, π–π stacking, hydrogen‐bonding and hydrophobic–hydrophobic interactions, these complexes are preorganized to readily undergo topochemical polymerization reactions upon photoirradiation. The in situ polymerization of the diacetylene units to form polydiacetylene, indicated by the UV/Vis spectral changes, gel permeation chromatography and dynamic light scattering, was found to alter their assembly behaviours, as revealed by TEM images.
