Zirconium(IV) oxynitrate hydrate catalyzed efficiently the condensation reactions of indoles and aldehydes in acetonitrile, under ambient conditions. The bis- or tris(indolyl)methane products were then dehydrogenated in one pot by using a stoichiometric amount of DDQ, to give conjugated chromophores that showed feasible applications as new pH indicators with excellent sensitivity in the pH range 8-10. Hypsochromic effects were observed in the presence of transition metal cations in acetonitrile with a significant color change for cobalt(II).
