Two new intercalates of tris[4-(pyridin-4-yl)phenyl]amine (TPPA) with zirconium hydrogen phosphate and zirconium 4-sulfophenylphosphonate having formulae Zr(HPO4)2•0.21(C33H24N4)•2.5H2O and Zr(HO3SC6H4PO3)1.3(C6H4PO3)0.7•0.35(C33H24N4)•2.5H2O were prepared and characterized by thermogravimetry, IR spectroscopy, and powder X-ray diffraction. The TPPA molecule has been selected as a model tripodal push-pull system with three peripheral basic centers that may undergo protonation. Their protonation afforded HTPPA/MeTPPA molecules with enhanced intramolecular charge-transfer (ICT). Intercalation of TPPA into layered zirconium hydrogen phosphate and zirconium 4 sulfophenylphosphonate led to its significant organization and protonation.
