The single-step excitation of the electrons over the sensitizer molecules anchored at the TiO₂ semiconductor serves as a driving source to facilitate the electron effect transfers, thus prompting the visible-light driven photocatalytic hydrogen generation activities. Though many review articles that evaluate the performance of such dye-sensitized semiconductor particulate systems are available in the literature, research progress made in the last few years since 2016 is not yet systematically reviewed. In this article, we therefore, systematically review the development of new dye-sensitizers that include metal-free organic dyes, metal-based sensitizers, and donor-bridged-acceptor (D-π-A) type dye-sensitizers, and their performances in sensitization of the TiO₂ semiconductor photocatalyst towards visible light driven hydrogen generation through water splitting. It has been chronicled that the aforesaid sensitizers are capable of harvesting a broader part of the solar spectrum, and could achieve photocatalytic H₂ production with varying degrees of success. The results discussed in this review afford a significant scope of rationalizating the factors that govern the H₂ production activity over the dye-modified TiO₂ photocatalyst, and provide a basis for further research towards the realization of high-performing dye-sensitized H₂ production photocatalytic system. The prospect of artificial intelligence (AI)-machine learning (ML) based modeling for quicker design and development of dye-sensitized TiO₂ based photocatalytic solar to fuel conversion system has been briefly discussed in the article.</p></div>","PeriodicalId":376,"journal":{"name":"Journal of Photochemistry and Photobiology C: Photochemistry Reviews","volume":"57 ","pages":"Article 100621"},"PeriodicalIF":13.6,"publicationDate":"2023-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"2291865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the main aims to improve the efficiency of these low-to-high photon-energy conversion is to reduce energy losses during the intersystem crossing (ISC). Since 2015, many strategies have been reported to address this challenge and a significant update has been noticed in this field. This review is aimed to critically analyze these updates and provide an outlook for the future. A detailed mechanism of ISC in thermally activated delayed-fluorescence (TADF) molecules that possess a small singlet−triplet energy gap, is discussed with a focus on its deeper understanding and the impact of molecular design. In this context, a range of selected organic and inorganic TADF molecules are thoroughly evaluated. Osmium(II) complexes that exhibit a spin-forbidden metal-to-ligand charge-transfer (</span></span>³<span>MLCT) transition in their Vis-NIR-IR absorption spectra and can be excited directly into their triplet state, thereby bypassing the energy loss during ISC, are also debated in sufficient detail for their advantages as well as shortcomings in being used in TTA-PUC. This work aims at reviewing the latest progress in this field, understanding the fundamental ISC mechanism of these photosensitizers, and critically addressing the challenges that are faced in this field. This review is anticipated to serve as a helpful script for identifying future directions and designing molecular sensitizers for TTA-PUC, which can sensitize the triplet state with minimum energy loss during ISC and can be helpful for increasing the anti-Stokes shift in TTA-PUC.</span></p></div>","PeriodicalId":376,"journal":{"name":"Journal of Photochemistry and Photobiology C: Photochemistry Reviews","volume":"56 ","pages":"Article 100618"},"PeriodicalIF":13.6,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41313141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The control of mtDNA replication and transcription is known to be mediated by noncanonical forms of guanine-rich nucleotides G-quadruplexes (G4s). These putative and transient guanine-based structures and their dynamics are closely associated with mtDNA deletion breakpoints pertaining to fatal diseases such as cancers, hypertension, diabetes, etc. The precise reason for the origin of G4s at deletion breakpoints in the heavy strand and during the replication process has not yet been identified, owing to its complex biochemical phenomenon. Biomolecular structure, typically having a size of 5–10 nm with an average life span of seconds, strongly demands high-end instruments to explore the precise biochemical mechanism and dynamics (folding or unfolding) in biological systems. In that sense, since the last decade, tremendous efforts have been kept in X-ray crystallography, circular dichroism spectroscopy (CD), nuclear magnetic resonance spectroscopy (NMR), immunofluorescence, and the mtG4-ChIP methods to recognize and characterize the G4s structures in physiological conditions.
