Elongated and substituted triazine-based tricarboxylic acid linkers for MOFs.

New triazine-based tricarboxylic acid linkers were prepared as elongated relatives of triazinetribenzoic acid (TATB). Additionally, functional groups (NO, NH, OMe, OH) were introduced for potential post-synthetic modification (PSM) of MOFs. Functionalized tris(4-bromoaryl)triazine "cores" (,) were obtained by unsymmetric trimerization mixing one equivalent of an acid chloride (OMe or NO substituted) with two equivalents of an unsubstituted nitrile.
