BODIPY-Based Molecular Probes: A Journey Through their Application in Photocatalysis, Singlet Oxygen Generation and...

Considering their interesting electronic and photonic properties, the 4,4-difluro-4-bora-3a, 4a-diaza-s-indacene (BODIPY)-based molecular probes are the cynosure in the current times. Their unique properties, such as easy functionalization through simple synthetic modifications, strong absorption and more importantly, the high fluorescence quantum yields, are the key attributes required for several Hi-tech applications. Consequently, in the last few decades, many research groups have diverted their attention to developing BODIPY-based materials for a wide range of applications. Motivated by the literature reports, in our previous review on this topic, we reported on systematic progress in the use of BODIPY-based derivatives in bioimaging applications covering the reports that appeared during 2014-2019. Since the BODIPY derivatives continue to inspire with their unique characteristics with the fascinating photophysical properties, in this present review we have surveyed the very representative and recent (2020 onwards) advancement in the applications of BODIPY-based molecular derivatives to catalysis, singlet oxygen generation and white light emission rationalised by the photoredox/electron transfer/energy transfer processes, and hope that this should be useful update to existing reviews on these topics.
