Optical sensing of aqueous boron based on polymeric hydroxytriphenylene derivatives

The detection of boron in natural water and wastewaters is still limited to a few methods, requiring a compromise between sensitivity, reliability and accessibility. Here we present a novel polymeric fluorescent boron sensor with excellent water solubility, boron sensitivity, ease of handling, which can be easily recovered and reused. The new off-on fluorescent boron sensor is able to detect and quantify ppb amounts of boron in water, with a limit of detection of 10 ppb of boron, both for boric acid and phenylboronic acid. The sensor was prepared by copolymerizing methacrylic acid with a polymerizable asymmetric hexa-substituted triphenylene, obtained by oxidative cyclization of biphenyl and catechol precursors.

Self-activated supramolecular reactions: Effects of host-guest recognition on the kinetics of the Diels-Alder reaction of open-chain oligoether quinones with cyclopentadiene

Diels-Alder reactions of acyclic oligoether-substituted quinones 1b, 1c, 2b, and 2c with cyclopentadiene were accelerated by the addition of alkali and alkaline earth metal perchlorates, and scandium trifluoromethane sulfonate (kc/kf

Neutral Ligands with Surfactant-Type Structure - Synthesis, Complexation, and Ion Transfer

New lipophilic neutral ligands which combine crown ether and podand characteristics with structural features of surfactants (cf. formulas 1-12, 16-26) were synthesized.Their complexation behaviour was studied, their solid-to-liquid and liquid-to-liquid phase transfer properties as well as their efficiency in ion transport across a liquid model membrane.Crystalline stoichiometric complexes of the cycles 2a-4a and of 3e with NaSCN, Ba(SCN)2, and BaI2 can be isolated.Among the noncyclic representatives a crystalline complex is obtained only from 11 with BaI2.The ligand 8d behaves in aqueous solution as a typical surfactant showing micelle formation and cloud point.
