3'-h]-quinoxaline; Medpq is 2-methyldipyrido[3,2-f:2',3'-h]-quinoxaline; Me(2)dpq is 2,3-dimethyldipyrido[3,2-f:2',3'-h]-quinoxaline and phen is 1,10-phenanthroline). The increase in electron density following substitution renders the quinoxaline nitrogen atoms more basic in the ground state to yield pK(a) values of -1.9, -2.3, and -2.7 for 3, 2, and 1, respectively. The methyl groups have a pronounced effect on

Photoreactive Ru (II) complexes are anchored on a G-containing oligonucleotide, e.g. compound 1. The method for obtaining them and their use, includes targeting specific nucleotide sequences that become photocrosslinked to the photoreactive Ru (II) complex anchored to the G-containing oligonucleotide.

Disclosed are surface immobilized (electro)catalysts that may be prepared by a condensation reaction that generates an aromatic unit that is robust to acid and base and elevated temperatures. Among their many desirable characteristics, the catalysts are far less prone to the bimolecular deactivation pathways commonly observed for homogeneous catalysts, and may be used in solvents with a range of polarities and dielectric strengths. The catalysts are suitable for a wide array of thermal catalytic reactions (polymerization, oxidation, hydrogenation, cross-coupling etc.) and as anodes and/or cathodes in fuel cells, electrolyzers, and in batteries and supercapacitors.
