Published in 2017 at "Journal of Chemical Crystallography"

DOI: 10.1007/s10870-017-0692-0

Abstract: AbstractFour pairs of isomeric aromatic heterocyclic dyes 1–8, synthesized from the diazotization and subsequent coupling reactions between 4 or 2-aminobenzoic acid as the diazo component and different N-substituted pyridone precursors as the coupling component, have… read more here.
