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...
