“…Lately, investigations regarding the scope of applications on BODIPYs for photocatalysis have been carried out with cobaloximes as a hydrogen evolution reaction (HER) catalyst. Typically, 1,3,5,7-tetramethyl-BODIPY bearing iodo substituents in 2 and 6 positions (DIB; Figure ) utilized pyridine or aniline in the meso position for electrostatic interaction toward the cobaloxime catalyst. , These investigations point out the high demand on noble-metal-free, organic PSs in photocatalytic applications. Sommer and co-workers reported a BODIPY bearing a para -(3-methyl)pyridyl substituent in the meso position, which achieved a maximum turnover number (TON) of 31 .…”

We report on a photocatalytic setup that utilizes the organic photosensitizer (PS) diiodo-BODIPY and the non-precious-metal-based hydrogen evolution reaction (HER) catalyst (NH4)2[Mo3S13] together with a polyampholytic unimolecular matrix poly(dehydroalanine)-graft-poly(ethylene glycol) (PDha-g-PEG) in aqueous media. The system shows exceptionally high performance with turnover numbers (TON > 7300) and turnover frequencies (TOF > 450 h–1) that are typical for noble-metal-containing systems. Excited-state absorption spectra reveal the formation of a long-lived triplet state of the PS in both aqueous and organic media. The system is a blueprint for developing noble-metal-free HER in water. Component optimization, e.g., by modification of the meso substituent of the PS and the composition of the HER catalyst, is further possible.

“…94 In our previous work, we observed the presence of both chargeseparated (NiO + jPC − ) and excited states (NiOjPC*) for photocatalysts with diester-functionalised bipyridine ligands. 62,63 In this case, for PC3, although most of the signal decays within 1 ns, there is evidence for successful charge-separation with the formation of NiO + jPC3 − .…”

“…The dynamics of the light-driven processes determined via studies of analogous chromophores in dilute solution do not directly transfer to the equivalent DS-PEC device. 62,63 Electron transfer from a dye/catalyst anchored to a semiconductor surface by the traditional strategy of an acid or phosphonate anchoring group leads to multiple competing recombination pathways, many similar to those seen with DSSCs. 57,[64][65][66][67] It is also now known that the chromophore's anchoring group itself can have a signicant impact on charge-recombination.…”

“…The purpose of this review is to present the up-to-date progress of BODIPY in biomedical applications. At the same time, besides biomedicine, BODIPY molecules have also been widely used in organ photovoltaic devices, [72,73] organic optoelectronic devices, [74][75][76] and photocatalytic organic reactions [77][78][79] fields, and many exciting results have been achieved in recent progress. Nevertheless, it still needs to be pointed out that the detailed and systematic discussion of those issues is beyond the scope of this review.…”

owing to its large molar absorption coefficients, high emission quantum yields, satisfactory chemical stability, and high tunability of photophysical properties. [10,11] The conventional BODIPY core has good structural stability, in which BF 2 -chelated inhibits the rotation around the CN pyrrole bridging bonds, which enhances the structural rigidity and endows the system with fluorescence emission properties. [12] The BODIPY core has 8 covalently modified positions, which can be divided into pyrrole ring carbons, the meso-carbon, and the boron atom. [11,13,14] These abundant active sites provide lots of possibilities to expand the structure of BODIPY derivatives through functionalization and to tune their photophysical properties. [15] In the past few decades, the structural modification strategies of BODIPY units and the resulting effects have been systematically explored, [4,16] providing a solid research foundation for the current-stage design and construction of various functional BODIPY derivatives for different occasions. After decades of development, by virtue of the high molar extinction coefficient, longer wavelength absorbing, outstanding photosensitivity, satisfactory internal stability, better biocompatibility relative to inorganic dyes, high light-dark toxicity ratios, and preferable photothermal conversion efficiency (PCE), [4,[17][18][19] there has been considerable interest in exploring the application of BODIPY as photosensitizers (PSs) in the area of phototherapy, which involves the production of reactive The use of boron dipyrromethene (BODIPY) in biomedicine is reviewed. To open, its synthesis and regulatory strategies are summarized, and inspiring cutting-edge work in post-functionalization strategies is highlighted. A brief overview of assembly model of BODIPY is then provided: BODIPY is introduced as a promising building block for the formation of single-and multicomponent self-assembled systems, including nanostructures suitable for aqueous environments, thereby showing the great development potential of supramolecular assembly in biomedicine applications. The frontier progress of BODIPY in biomedical application is thereafter described, supported by examples of the frontiers of biomedical applications of BODIPY-containing smart materials: it mainly involves the application of materials based on BODIPY building blocks and their assemblies in fluorescence bioimaging, photoacoustic imaging, disease treatment including photodynamic therapy, photothermal therapy, and immunotherapy. Lastly, not only the current status of the BODIPY family in the biomedical field but also the challenges worth considering are summarized. At the same time, insights into the future development prospects of biomedically applicable BODIPY are provided.
