TMU-34(-2H), [Zn(OBA)(DPT)0.5].DMF, has been sonochemically synthesized by applying H2OBA, (4,4′-oxybis(benzoic acid)), as the dicarboxylate linker, and DPT, (3,6-di(pyridin-4-yl)-1,2,4,5-tetrazine), as pillar spacer. Sonication time, concentration of initial reagents, sonication power and molar ratio of pyridine as modulator has been optimized to synthesize nano powder of TMU-34(-2H) including uniform plate morphology. Nano TMU-34(-2H), can detect phenylhydrazine (PH) by color changing from pink to deep purple. As a comparison, nano and crystal samples of TMU-34(-2H) were treated to detect PH. Experiments show that nano TMU-34(-2H) has better detection limit and response time.
