The molecular structures of the ground and the lowest triplet states for a series of Pt（ll） complexes PtLCl（l）[L=6-（2-hydroxyphenyl）-2,2＇-bipyridine], Pt（pp）2[pp=2-（2-hydroxyphenyl）pyridine]（2）, PtbpyClz（bpy=2,2＇- bipyridine）（3）, and the free tridentate L ligand（4） were optimized by the density functional theory B3LYP and UB3LYP methods, respectively. On the basis of optimized geometries, the spectral properties were investigated with time-dependent density functional theory（TD-DFT）. In comparison with those of complexes 2 and 3, the more rigid structure of complex 1 together with its low rate of the radiationless decay via nonemissive d-d state leads to higher photoluminescence quantum efficiency. And the phosphorescence quantum efficiency of complex 1 can be easily controlled by modifying auxiliary ligands. The introduction of fluorine ligand into complexes can effectively increase the radiation transition rate and decrease the radiationless d-d transition rate, and as a result, a novel complex PtLF（5） might be a good phosphorescent material suitable for organic electronic devices.

An organic compound exhibiting simultaneously reversible switch between its emission colors and luminescence mechanisms,possessing high contrast from deep blue normal fluorescence(NF) to yellow thermally activated delayed fluorescence(TADF),is reported. Based on these two complementary colors, white-light emission combining NF and TADF from a single compound can be achieved in various states. Experimental results and density functional theory calculations indicate that the controllable conformational distribution under thermal and mechanical activation is the mechanism responsible for the reversible switching behavior.
