Abstract
Multi-branched probes based on 2-hydroxymethylene 8-dimethylaminoquinoline (8-DMAQ) and triphenylamine (TPA) have been synthesized and compared under UV and femtosecond near-infrared two-photon (2P) activation conditions. While octupolar (3) and quadrupolar (2) DMAQ derivatives showed superior ε and 2P absorption cross-section (σ2) values relative to the dipolar (1) probe, the fragmentation efficiency exhibited an inverse correlation with the enhanced absorption. Compound 1 emerged as the most effective probe reported to date for the release of organic substrates under both UV and 2P activation conditions at wavelengths accessible to commercially available lasers, achieving a quantum yield (Q) of 12% with σ2 = 86 GM and uncaging cross-section δu = 10.2 GM at 735 nm.
期刊介绍：
Chemistry—A European Journal is a truly international journal with top quality contributions (2018 ISI Impact Factor: 5.16). It publishes a wide range of outstanding Reviews, Minireviews, Concepts, Full Papers, and Communications from all areas of chemistry and related fields.
Based in Europe Chemistry—A European Journal provides an excellent platform for increasing the visibility of European chemistry as well as for featuring the best research from authors from around the world.
All manuscripts are peer-reviewed, and electronic processing ensures accurate reproduction of text and data, plus short publication times.
The Concepts section provides nonspecialist readers with a useful conceptual guide to unfamiliar areas and experts with new angles on familiar problems.
Chemistry—A European Journal is published on behalf of ChemPubSoc Europe, a group of 16 national chemical societies from within Europe, and supported by the Asian Chemical Editorial Societies. The ChemPubSoc Europe family comprises: Angewandte Chemie, Chemistry—A European Journal, European Journal of Organic Chemistry, European Journal of Inorganic Chemistry, ChemPhysChem, ChemBioChem, ChemMedChem, ChemCatChem, ChemSusChem, ChemPlusChem, ChemElectroChem, and ChemistryOpen.
