摘要
A series of tetra de ntate Pd(ll)and Pt(ll)complexes containing fused 5/6/6 metallocycles with phe nyl/V-heteroaromatic ben-zo[d]imidazole(pbiz),benzo[d]oxazole(pboz)or benzo[d]thiazole(pbthz)-containing ligands was developed.Systematic studies by experiments and theoret:ical calculations reveal that both the central metal and the benzannulated A/-heteroaromatic ring have sig-n ificant in flue nee on the electrochemical,photophysical and excited-state properties of the Pd(ll)and Pt(ll)complexes.In identical condition,compared to pb/z-based Pd(ll)and Pt(ll)complexes,the corresponding metal complexes with pboz and pbthz-containing ligand show significant red-shift emission spectra.
