DFT calculations revealed two conformations of the essentially planar diradical core, <em>anti</em> and <em>syn</em>, with opposite spin ground states and comparable populations at ambient temperature equilibrium. This indicates that solution spectroscopic and electrochemical analyses involve mixtures of two conformers and thermally populated spin states. Consequently, analysis of variable temperature EPR data for the diradicals in polystyrene solid solutions included the presence of two conformers and gave the singlet–triplet energy gap for each of them Δ<em>E</em><small><sub>S–T</sub></small> of 1.02(5) and −0.45 kcal mol<small><sup>−1</sup></small> for the C(3′)–C(6) connected diradical, and 1.78(3) and −0.10 kcal mol<small><sup>−1</sup></small> for its C(3′)–C(7) isomer. The observed trend in Δ<em>E</em><small><sub>S–T</sub></small> is consistent with that obtained with DFT methods. Optical spectroscopy revealed broad absorption bands tailing to 1150 nm, presumably due to the presence of the open-shell singlet species in each diradical. Both diradicals exhibit four quasi-reversible one-electron redox processes separated by 0.13–0.27 V. The structure of the two diradicals was confirmed with a single crystal XRD analysis. Results for this prototypical pair of isomeric diradicals suggest a simple and efficient access to an unusual family of chemically stable, dynamic Blatter diradicals with the controllable overall concentration of the triplet species through a judicious choice of substituents. DFT calculations indicate that the Δ<em>E</em><small><sub>S–T</sub></small> of each conformer and the ratio of the conformers is affected by substituents at the C(3), C(6′)/C(7′), and N(1)/N(1′) positions and the concentration of the triplet species can be varied in a range of 50–77% at 298 K.</p>","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 20","pages":" 3344-3357"},"PeriodicalIF":6.0,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142202668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast, seawater represents an abundant and underutilized source, comprising 97% of the world's total water supply. Electrocatalytic seawater splitting (ESS) thus emerges as a promising method for generating clean hydrogen (H<small><sub>2</sub></small>) fuel. However, a significant challenge in seawater splitting lies in the electro-oxidation of dissolved ions at the anode, which leads to severe electrode corrosion and competes with the oxygen evolution reaction (OER), thereby reducing its efficiency. Despite the utilization of various electrocatalysts, achieving high current densities for seawater splitting without side reactions remains a formidable task. Recent literature has seen a surge in research focusing on transition metal-based catalysts for this purpose. Metal–organic frameworks (MOFs) have garnered attention in electrocatalysis due to their unique properties, although their application in seawater electrolysis is relatively new compared to alkaline water splitting. To date, numerous studies have been published on MOFs and MOF-based materials for electrocatalytic seawater splitting. However, there is a lack of comprehensive articles summarizing these advancements. This article aims to address this gap by providing an overview of recent progress on MOFs and MOF-based materials tailored specifically for seawater electrolysis. We systematically discuss the relationships between structure, properties, and performance of various MOFs and MOF-based materials, supported by notable examples from recent research. Additionally, we examine how the structural characteristics, morphology, and electronic properties of MOFs influence their effectiveness in seawater electrolysis. Furthermore, the article explores future opportunities and challenges in the field, offering insights into the prospects and obstacles associated with advancing and implementing MOFs and MOF-based materials for seawater electrolysis.</p>","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 19","pages":" 3136-3149"},"PeriodicalIF":6.0,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142202645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among various types of photosensitizers, BODIPY dyes are potential candidates for phototherapy owing to their high molar extinction coefficient and tunable photophysical properties. However, most NIR BODIPY photosensitizers have relatively complicated structures and lengthy synthesis approaches, restricting their practical application. In this work, a simple strategy of chalcogen modification was applied to tune the photophysical properties of iodinated BODIPY for enhanced NIR phototherapy. As the atomic radius of chalcogen atoms increases, the BODIPY-X (X = O, S, Se, and Te) dyes exhibit a red-shifted absorption from 558 nm, 610 nm, and 618 nm to 660 nm, a faster singlet oxygen generation rate, and higher photothermal conversion efficiency due to the heavy atom effect. This modification facilitates intramolecular charge transfer (ICT) and enhances intersystem crossing (ISC), critical for effective PDT and PTT. To improve hydrophilicity and delivery efficiency, we encapsulated BODIPY-X using the amphiphilic copolymer Pluronic F127, creating F127/BODIPY-X nanoparticles (NPs). These NPs exhibited enhanced solubility and bioavailability, crucial for therapeutic efficacy. Moreover, the F127-encapsulated BODIPY-Te nanoparticles exhibit the best anti-tumor efficiency on U87-bearing mice, which is consistent with their outstanding photothermal conversion and photodynamic performance. Hence, a chalcogen modification strategy with a simple synthesis approach paves a new way for tuning the photophysical properties of NIR photosensitizers and could stimulate the rapid development of NIR phototheranostic agents.</p>","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 20","pages":" 3308-3320"},"PeriodicalIF":6.0,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141872300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
