چکیده
Two novel luminescent rhenium(I) diimine indole complexes have been designed and their properties studied; these conjugates can be recognised by indole-binding proteins including bovine serum albumin, lysozyme and tryptophanase.

Luminescent conjugates between dinuclear rhenium(I) complexes and peptide nucleic acids (PNA) for cell imaging and DNA targeting.
New luminescent dinuclear rhenium(I) tricarbonyl complex-PNA conjugates have been synthesized through a reliable solid-phase synthetic methodology. Their photophysical properties have been measured. The most luminescent Re-PNA conjugate 7 showed interesting two-photon absorption (TPA) properties, that were exploited for imaging experiments, to demonstrate its easy uptake into living cells.
متن کاملLuminescent rhenium(I) complexes with acetylamino- and trifluoroacetylamino-containing phenanthroline ligands: anion-sensing study.
A series of rhenium complexes with acetylamino- and trifluoroacetylamino-containing 1,10-phenanthroline ligands have been synthesized, characterized and their photophysical and electrochemical properties studied. These complexes were found to show significant UV-vis and emission changes on addition of CN(-), F(-) and AcO(-) anions. Their reactivity towards CN(-), F(-) and AcO(-) anions, was als...

A strongly absorbing and significantly luminescing diimine ligand, N,N -diphenyl-p-(benzyl-1,3,4-oxadiazole)-2,2 -bipyridine (DPO-bpy), incorporating -conjugated oxadiazole linkage units and remote triphenylamine groups has been synthesized and characterized, as have the corresponding mononuclear metal complexes, fac-(DPO-bpy)Re(CO)3Cl and fac-(DPObpy)Mn(CO)3Br. The rhenium complex was structur...

We developed new cyclic Re(I)-based trinuclear redox photosensitizers with both high oxidation power in the excited state and strong reduction power in the reduced form. These excellent properties were achieved by introducing electron-donating groups on the diimine ligand of the Re(I) metal centre and by connecting each Re(I) unit with polyphenyl–bisphosphine bridging ligands. These Re-rings we...
متن کاملNovel luminescent iminephosphine complex of copper(I) with high photochemical and electrochemical stability.
Luminescent heteroleptic Cu(I) complexes based on asymmetrical iminephosphine ligands exhibit improved electrochemical and photochemical stability as compared to the analogous complexes based on traditional diimine or diphosphine ligands.
