Design and synthesis of new nanosized C 3-symmetrical tricarboxylic acids: Key elongated ligands for the preparation of highly porous MOFs

Abstract

The synthesis of two new C 3-symmetrical nanosized tricarboxylic acids bearing triphenylmethane cores and three imines linkages is presented. The new elongated tripods were designed to stabilise highly porous metal-organic frameworks (MOFs) and were synthesized by a threefold Schiff base condensation reaction between the reduced leuco form of pararosaniline hydrochloride salt and an appropriate aldehyde. © 2015 Georg Thieme Verlag Stuttgart · New York.
