Homoleptic bis(aryl)acenaphthenequinonediimine-CuI complexes-Synthesis and characterization of a family of compounds with improved light-gathering characteristics

A group of bis(aryl)acenaphthenequinonediimine (Ar-BIAN) ligands were synthesized through a modified procedure, which bypasses the need for absolutely dry conditions during the initial template synthesis. The molecular and electronic structure of the corresponding homoleptic [Cu(Ar-BIAN) 2]BF4 complexes were probed by means of a variety of spectroscopic methods. In accord with solution 13C NMR spectra, X-ray crystallography reveals D2 or approximate D2 symmetry for the [Cu(p-Cl-BIAN)2]+ and [Cu(p-Me-BIAN) 2]+ cations and noncrystallographic C2 symmetry for the [Cu(o-Ph-BIAN)2]+ cation. The structures of the p-Cl-, p-Me, and o-Ph-BIAN complexes agree with the presence of ligands in their neutral form according to the lengths of the relevant C-C and C=N bonds of the organic skeleton. The concerted stereo-electronic effects of the substituents on the aryl rings affect the electron donor/acceptor capacities of the ligands and the structures of the complexes, as the study of the visible absorption spectra of the complexes indicates. The spectra of the complexes are dominated by intense and broad metal-to-ligand charge transfer (MLCT) bands that enter the near-infrared (NIR) region. Additionally, electrochemical studies undertaken reveal several successive electron capture and release processes, which further manifest the redox versatility of the ligands. Bis(aryl) acenaphthenequinonediimine (Ar-BIAN) ligands form complexes with CuI that absorb in the visible and near-infrared (NIR) regions. The ligand substituents have a profound effect on the energy and intensity of the metal-to-ligand charge transfer (MLCT) absorption. Despite the redox activity of the ligands, neither the copper center nor the ligands change oxidation state after complexation. Copyright

Bis(aryl)acenaphthenequinonediimine substituent effect on the properties and coordination environment of ligands and their bis-chelate AgI complexes

The reaction of a series of Ar-BIAN ligands (Ar = o-Ph, m-Cl, m-CF 3, p-Cl, p-MeO, and p-Me-C6H4) with AgNO 3 results in the formation of the corresponding bis-chelate complexes. Substituent groups on the aryl rings seem to offer tunability of the electronic properties of the diimines, also affecting the metal coordination environment through the mono-coordination or chelation of the nitrate anion as promoted by the substituents p-MeO, p-Me, and m-CF3. The enhanced absorption capacity of the complexes in the visible region in combination with the well-known redox activity of the ligands and their ability to potentially accommodate a fifth coordinated ligand on the metal center opens a route for the preparation of new silver species of high propensity for catalytic, photocatalytic, and biological applications. Six new AgI-bis(BIAN) complexes along with their ligands were synthesized and studied. Substituent groups offer tunability of the electronic properties and structural environment of the compounds. The versatility on the metal coordination sphere opens the way for the design of photoactive species with a variety of applications. Copyright
