Pt.sub.2M heterotrinuclear metal-organic alkynyl complexes have a structure of formula (I): [Pt.sub.2M(μ-PR.sub.2CH.sub.2PRCH.sub.2PR.sub.2).sub.2(C≡CR′).sub.2(C≡CR″).sub.2].sup.+.sub.mA.sup.m−. In formula (I), μ represents a bridging ligand; PR.sub.2CH.sub.2PRCH.sub.2PR.sub.2 is a type of tridentate phosphine ligands; the subscript number of each letter represents the number of each group. The complexes present phosphorescent emission, and the color distribution of the emitted light is relatively broad from blue-green to orange-red. The complexes can be used as photoluminescent materials in the fields of displays, lighting, sensors and biomarkers. Among the complexes, Cu complexes also exhibit reversible self-recovery photochromic performance. Under UV irradiation, the complexes change from a colorless or light color state to a dark color state rapidly, and after stopping UV irradiation, they gradually return to the light color state.
