Two-photon photosensitized production of singlet oxygen: Sensitizers with phenylene-ethynylene-based chromophores

(Chemical Equation Presented) Singlet molecular oxygen (a 1Δg) has been produced and optically monitored in time-resolved experiments upon nonlinear two-photon excitation of photosensitizers that contain triple bonds as an integral part of the chromophore. Both experiments and ab initio computations indicate that the photophysical properties of alkyne-containing sensitizers are similar to those in the alkene-containing analogues. Most importantly, however, in comparison to the analogue that contains double bonds, the sensitizer containing alkyne moieties is more stable against singlet-oxygen-mediated photooxygenation reactions. This increased stability can be advantageous, particularly with respect to two-photon singlet oxygen imaging experiments in which data are collected over comparatively long time periods.

A polyanionic dendritic fluorophore for selective detection of Hg 2+ in triton X-100 aqueous media

A serles of water-soluble fluorescent dendritic compounds composed of phenylene-ethynylene repeating units and anionic carboxylate or catlonlc ammonium peripheral groups were synthesized. The first generation fluorescent dendrlmer containing nine phenylene-ethynylene units and six carboxylate peripheral groups exhibited a highly selective fluorescence quenching by Hg 2+ Ions. The Stern-Volmer constant (K8v) was 33,700 M -1 In aqueous media In the presence of Triton X-100 surfactant.
