As a Zn2+ fluorescent probe, we have designed and synthesized new type of calixarene Schiff-base ligand (L) possessing 1-phenylethylamine group as the fluorophore receptor. only caused significant increase in fluorescence emission intensity at 480 nm limit detection (LOD) reached 4.8 x 10-7 M, probe L demonstrated high selectivity sensitivity towards compared to other metal ions. In addition, f...

We report the proton affinities (PAs) and gas-phase basicities (GBs) of pyrogallol (1,2,3-trihydroxybenzene) phloroglucinol (1,3,5-trihydroxybenzene), as determined by high level quantum chemical calculations a series isodesmic transfer reactions. These yet unmeasured values have relevance to release active species from nanocarriers derived calixarene family macrocycles. The PAs GBs obtained fo...
