The biscatechol, H4BP (4,4’-bis(3-tert-butyl-1,2-catechol)) that connects two redox active catechol moieties directly was synthesized. Also, tpa (tris(2-pyridylmethyl)amine), bpqa (bis(2-pyridylmethyl)(2-quinolylmethyl)amine), pbqa ((2-pyridylmethyl)bis(2-quinolyl methyl)amine), and tqa (tris(2-quinolylmethyl)amine) were synthesized as terminal ligands...
