Abstract
Alkyl substitution at the pyridyl periphery of 1, 3, 5, 7-tetra (2-pyridylimino)-benzodipyrroles provides bis chelating ligands with unexpected increase in organic solubility. The bis-chelating ligands may be used to form organometallic polymers as well as being suitable as dyes and metal ion deactivators. The metal complexes of such bis-chelating ligands may also be used as dyes.
