Aminobenzenecarboxylic acids

In organic solvents the acidity functions H corresponding to hydrogen dissociation from neutral indicator acids were reported for solutions of alkali metal alkoxides in various alcohols (2), using nitroanilines (21), aminobenzenecarboxylic acids (22), or indols (23) as indicators. For addition reactions of methoxide and ethoxide ions to neutral indicator acids, acidity functions J (also denoted as Hr) based on use of nitrobenzenes (21) and a-cyanostilbenes (18) as indicators in methanol and dimethylsulfoxide-methanol and -ethanol mixtures were reported. Recently (24) the acidity function J- (denoted as Jm) was derived for methoxide ion solutions in methanol using substituted benzaldehydes as indicators. These scales involve arbitrary choice of water as the solvent for determination of the dissociation constant of the anchoring acid. 

The tbo net is another prototypical platform for MOFs. The most famous example is HKUST-1 synthesized from trimesic acid (H3BTC) and copper salts. Yaghi and coworkers reported that using longer variants of BTC ligand such as 4,4, 4"-s-triazine-2,4,6-triyltribenzoate (TATB), 4,4, 4"-s-triazine-l,3,5-triyltrip-aminobenzenecarboxylic acid (H3TATAB), 4,4, 4"-(1,3,4,6,7,9,9b-heptaazaphenalene-2,5,8-triyl)tribenzoate...
