A new decadentate dinucleating ligand containing a pyridazine bridging group and pyridylic arms has been synthesized and characterized by analytical and spectroscopic techniques. Four new dinuclear cobalt complexes featuring this ligand have been prepared and thoroughly characterized both in the solid state (X-ray diffraction) and in solution (1D and 2D NMR spectroscopy, ESI-MS, and electrochem...

In this article, we study the photoinduced electrochemiluminescence (PECL) of a luminol analog (L-012: 8-amino- 5‑chloro-2,3-dihydro-7-phenyl-pyrido[3,4-d]pyridazine-1,4‑dione) on n-type hematite (α-Fe2O3) nanorod arrays deposited by hydrothermal synthesis transparent conducting oxide. We report that material, when used as photoanode, triggers PECL at potential low -0.2 V vs Ag/AgCl and allows ...
