Abstract
We report an optimized and scalable synthesis of BOPYRENPY, a seven-membered BF2-chelated chromophore, improving yields from 10% to almost 90%, on a multigram scale via acetonitrile-mediated stabilization of BF3 intermediates. This approach enabled the first covalently linked seven-membered BF2-C60 dyad, previously inaccessible due to low precursor availability. Optical and electrochemical studies demonstrate efficient intramolecular energy and electron transfer to the fullerene triplet state, driving the generation of reactive oxygen species (ROS) and establishing a new heavy-atom-free triplet photosensitizer platform for ROS-mediated applications.
期刊介绍:
Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
