Synthesis, structural, and photophysical investigation of diimine triscarbonyl Re(I) tetrazolato complexes.

摘要: The synthesis, structural, and photophysical properties of a novel family neutral fac-[Re(N∧N)(CO)3(L)] complexes, where N∧N is either 2,2′-bipyridine or 1,10-phenanthroline L para functionalized 5-aryltetrazolate [namely, 5-phenyltetrazolate (Tph−), 4-(tetrazolate-5-yl)benzaldehyde (Tbdz−), 5-(4-acetylphenyl)tetrazolate (Tacy−), methyl 4-(tetrazolate-5-yl)benzoate (Tmeb−)] are reported. complexes were prepared by direct addition the corresponding tetrazolate anion to acetonitrile solvated fac-[Re(N∧N)(CO)3]+ precursor. NMR data demonstrate that coordination metal fragment regiospecific at N2 atom ring. These conclusions also supported X-ray structural determinations. Photophysical obtained in diluted deaerated dichloromethane solutions displaying broad structureless profiles with emission maxima ranging from 566 578 nm. absorption indicate presence higher energy intraligand (IL) π−π* transition...
