Phosphorescence of hexachlorosubstituted subphthalocyanine and its pyrazine analogue

Perchlorinated vanadyl tetrapyrazinoporphyrazine: spectral, redox and magnetic properties

“…Most probably, mono-reduced [(Cl 8 TPyzPz˙ 3− )V IV O] − radical anion cannot be generated at the reduction of starting material due to its strongly acceptor nature and easily undergoes further reduction. Previously, namely doubly reduced species [(Cl 16 Pc 4− )Sn IV Cl 2 ] 2− and [(Cl 8 TPyzPz 4− )Sn IV Cl 2 ] 2− 31 were obtained at the reduction of perchlorinated Pc and TPyzPz macrocycles by mild reductant – fullerene radical anion as {cryptand(Na + )}(C 60 ˙ − ) ( E redox = −0.6 V vs. SCE 34 ). We also tried to obtain triply reduced form.…”

“…25 Recently a similar combined effect on redox and spectral luminescence properties has been reported for boron( iii ) complexes of perhalogenated pyrazine analogues of subphthalocyanine. 25,30,31 In this work we synthesized and studied crystal structures, optical, redox and magnetic properties of [Cl 8 TPyzPzVO].…”
