| Description
| - Azophenin (7,8-diphenyl-2,5-bis(phenylamino)-p-quinonediimin, Lp) reaguje s [Cu(PPh3)4](BF4) nebo Re(CO)5Cl za vzniku (Ph3P)2Cu+ nebo (OC)3ClRe komplexů tautomerické formy 7,8-diphenyl-4,5-bis(phenylamino)-o-quinonediiminu, Lo, jak vyplývá z určené struktury a velmi intensivních přechodů přenosu náboje kov - ligand (MLCT) ve viditelné oblasti spektra. Výpočty pomocí časově závislé DFT metody (TD-DFT) pro komplex (N^N)Re(CO)3Cl potvrdily spektroskopické výsledky, a ukázaly na výrazně vyšší síly oscilátoru pro MLCT přechody o-quinonediiminových komplexů ve srovnání s N^N = 1,4-dialkyl-1,4-diazabutadienovými komplexy.

- Azophenine (7,8-diphenyl-2,5-bis(phenylamino)-p-quinonediimine, Lp) reacts with [Cu(PPh3)4](BF4) or Re(CO)5Cl to yield the (Ph3P)2Cu+ or (OC)3ClRe complex of the tautomeric form 7,8-diphenyl-4,5-bis(phenylamino)-o-quinonediimine, Lo, as evident from structure determinations and from very intense metal-to-ligand charge transfer (MLCT) transitions in the visible region. Time-dependent DFT (TD-DFT) calculations on model complexes (NN)Re(CO)3Cl confirm the spectroscopic results, showing considerably higher oscillator strengths of the MLCT transition for the o-quinonediimine complexes in comparison to compounds with NN = 1,4-dialkyl-1,4-diazabutadiene. The cationic copper(I) complex is additionally stabilized through hydrogen bonding between two now ortho-positioned NHPh substituents and one fluoride of the BF4- anion. DFT Calculations on the model ligands p-quinonediimine or 2,5-diamino-p-quinonediimine and their ortho-quinonoid forms with and without Li+ or Cu+.
