Molecular encapsulation in pyrogallolarene hexamers under nonequilibrium conditions.

Jennifer C Chapin et al.

Journal of the American Chemical Society, 134(36), 15000-15009 (2012-09-04)

Pyrogallol[4]arene is a macrocycle with a concave surface and 12 peripheral hydroxyl groups that mediate its self-assembly to form hexamers of octahedral symmetry in the solid state, in solution, and in the gas phase. These hexamers enclose approximately 1300 Å(3)

Bathochromic and stabilising effects of sugar beet pectin and an isolated pectic fraction on anthocyanins exhibiting pyrogallol and catechol moieties.

M Buchweitz et al.

Food chemistry, 135(4), 3010-3019 (2012-09-18)

The formation of anthocyanin-metal chelates, exhibiting intense blue colours was monitored over a period up to 10 weeks. Evaluating normalised absorption spectra in the range of 580-700 nm and their proportion of the total area under the curve (AUC), provided

Nafion-mercury coated film electrode for the adsorptive stripping voltammetric determination of lead and cadmium in the presence of pyrogallol red.

Edgar Nagles et al.

Talanta, 99, 119-124 (2012-09-13)

An adsorptive stripping voltammetric (AdSV) method is presented for the simultaneous determination of Pb(II) and Cd(II) at trace levels in natural waters, based on metal complexation with pyrogallol red (PR) and subsequent adsorptive deposition on a Nafion-mercury coated glassy carbon

Spectrophotometric determination of sulfide based on peroxidase inhibition by detection of purpurogallin formation.

Mohammad Ghadiri et al.

Ecotoxicology and environmental safety, 91, 117-121 (2013-02-26)

This paper presents a new method for spectrophotometirc detection of sulfide applying fungal peroxidase immobilized on sodium alginate. The sensing scheme was based on decrease of the absorbance of the orange compound, purpurogallin produced from pyrogallol and H2O2 as substrates

Stable, hydroxyl functional polycarbonates with glycerol side chains synthesized from CO(2) and isopropylidene(glyceryl glycidyl ether).

Jeannette Geschwind et al.

Macromolecular rapid communications, 34(2), 150-155 (2012-11-30)

A series of functional polycarbonates, poly((isopropylidene glyceryl glycidyl ether)-co-(glycidyl methyl ether) carbonate) (P((IGG-co-GME) C)) random copolymers with different fractions of 1,2-isopropylidene glyceryl glycidyl ether (IGG) units, is synthesized. After acidic hydrolysis of the acetal protecting groups, a new type of
