Photochromic Pt(II)-M(I) heterotrinuclear complexes, preparation method therefor and use thereof |
| abstract |
Pt2M heterotrinuclear metal-organic alkynyl complexes have a structure of formula (I): [Pt2M(μ-PR2CH2PRCH2PR2)2(C≡CR′)2(C≡CR″)2]+mAm−. In formula (I), μ represents a bridging ligand; PR2CH2PRCH2PR2 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. |
