ResumoA series of new imidazo[1,5-a]pyridines was obtained through a facile multiple condensation procedure, involving the reaction of two methanamine and several largely available and inexpensive di- and tricarboxylic acids. Such poliazine products show different and tuneable coordination motifs suitable for mono-, di-, and tritopic coordination sites. Furthermore they display interesting optical properties: tuneable luminescence, significant quantum yields, large Stokes' shifts and strong halochromic effects, enabling their technological application.
