Animal rhodopsins act as G protein–coupled receptors, whereas microbial rhodopsins serve numerous roles and can act as light-driven ion pumps, photosensors, light-gated ion channels, and light-activated enzymes. Microbial rhodopsins play crucial roles in optogenetics. Isomerization is a shape-changing reaction that does not occur at low temperatures. In contrast, primary photo-intermediates are formed in rhodopsins even at 77 K. Therefore, the primary reactions in rhodopsins were debated in the 1970s, although isomerization was initially proposed. The ultrafast spectroscopy analysis of bovine rhodopsin containing an 11-cis-locked retinal chromophore revealed that the primary event in our vision is retinal photoisomerization. Moreover, molecular motions have been directly visualized by time-resolved x-ray crystallography. The unique ability of rhodopsins to undergo isomerization at 77 K was used to determine structural changes by low-temperature Fourier transform infrared spectroscopy, with detailed vibrational analysis providing structural information on animal and microbial rhodopsins, including protein-bound water. In contrast, unusual isomerization pathways (all-trans to 7-cis or 11-cis) and temperature effects (no reactions at <273 or <170 K) have been found for near-infrared light–absorbing microbial rhodopsins.","PeriodicalId":502275,"journal":{"name":"Chemical Physics Reviews","volume":"123 38","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141656712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The incorporation of photothermal effect into photocatalysis enables dual utilization of both light and heat energies, resulting in improved solar-to-hydrogen efficiency. In this review, we first discussed the behavior of energy flow and mass flow, and the characteristics of photogenerated carrier throughout the photocatalytic water splitting process, with particular focus on the behaviors induced by photothermal effect. Subsequently, we elaborate on strategies for designing high-efficiency photothermal catalytic systems and novel photothermal–photocatalytic integrated systems based upon concentrating-photothermal coupling effects. We then illustrate the development and large-scale demonstrations that utilize concentrated solar irradiation. Finally, we outline the challenges and highlight the future research directions of photothermal catalysis toward hydrogen production from water.

Developing these exciting properties to their fullest extent requires a thorough mechanistic understanding of the structure–function relationships. We implement an ultrafast spectroscopic toolset, femtosecond transient absorption and femtosecond stimulated Raman spectroscopy (FSRS), to elucidate the correlated electronic and vibrational dynamics of two isostructural 1,3,6,8-tetrakis(p-benzoic acid)pyrene (TBAPy)-based MOFs, which manifest drastically different photocatalytic behaviors. Systematic comparisons between the M3+-TBAPy MOFs and bare ligands in various environments reveal the unproductive dimer formation in Al-TBAPy, whereas Sc-TBAPy is dominated by a catalytically active charge-transfer (CT) process. Two ground-state FSRS marker bands of the TBAPy ligand at ∼1267 and 1617 cm−1 probe the chromophore environment at thermal equilibrium. For comparison, the excited-state FSRS of Sc-TBAPy suspended in neutral water unveils a key ∼300 fs twisting motion of the TBAPy peripheral phenyl groups toward planarity, promoting an efficient generation of CT species. This motion also exhibits high sensitivity to solvent environment, which can be a useful probe; we also showed the CT variation for ultrafast dynamics of Sc-TBAPy in the glyphosate aqueous solution. These new insights showcase the power of table-top tunable FSRS methodology to delineate structural dynamics of functional molecular systems in action, including MOFs and other photosensitive “nanomachines.” We expect the uncovered ligand motions (ultrafast planarization) to enable the targeted design of new MOFs with improved CT state characteristics (formation and lifetime) to power applications, including photocatalysis and herbicide removal from waterways.","PeriodicalId":502275,"journal":{"name":"Chemical Physics Reviews","volume":"99 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141002868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It represents a renewable feedstock for the synthesis of chemicals and materials. Its utilization has become an area of growing interest. Of lignocellulose components, lignin is comparatively under-explored and under-utilized, despite its abundance. This Focus Review recognizes this missed opportunity and presents a concise overview on some of the most recent progress involving the generation and application of functional materials derived from lignin. Between the two commonly encountered forms of lignin, technical lignin is a by-product of the paper production industry and is highly processed under harsh conditions. As such, it has generally been used for filler and resin materials. By comparison, native lignin is rich in chemical functionalities and holds great promise for downstream chemical synthesis. In recognition of these potentials, “lignin-first” strategies have emerged to directly convert native lignin to building blocks rich in functional groups, such as alcohols and carbonyls, while maintaining the integrity of the aromatic structures in lignin. The lignin-first strategy complements the already well explored field of technical lignin utilization. These chemoselective, lignin-first methods promise routes to native lignin valorization into high-value building blocks while keeping cellulose and hemicellulose intact and, therefore, are particularly appealing. This Focus Review first recognizes the importance of the traditional strategies for technical lignin utilization and highlights some of the newest developments. It then puts an emphasis on these lignin-first approaches for improved native lignin utilizations.","PeriodicalId":502275,"journal":{"name":"Chemical Physics Reviews","volume":"48 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140659758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These methods enable the rapid fabrication of complex 3D structures, utilizing either yield-stress support baths or self-supporting inks. Both these strategies have been extensively studied across a range of fields, including biomedical, soft robotics, and smart sensors, due to their outstanding print fidelity and compatibility with diverse ink materials. Particle additives capable of forming volume-filling 3D networks are frequently incorporated into polymer solvents. This integration is crucial for engineering the requisite microstructures essential for the formulation of successful support bath and ink materials. The interplay between the particle additives and polymer solvents is critical for achieving rheological tunability in various 3D printing strategies, yet this area has not been systematically reviewed. Therefore, in this critical review, we examined various mechanisms of particle–polymer interactions, the resulting microstructures, and their subsequent impact on mechanical and rheological properties.

Halide perovskites are known for their tunable properties, while chalcogenides are known for their high efficiency. The combination of these types of materials as heterostructures is thought to have been able to produce a superior device/photophysical performance. A peculiar aspect to consider is an inherent weak interaction between these layers via the stacking of different materials, promoting the realization of van der Waals heterostructures with novel functional properties. In this review, we summarize the progress and foresee the prospectives of material systems obtained by combining low-dimensional (0D, 1D, and 2D) halide perovskite and chalcogenide systems. Both emergent materials share their promise in terms of energy and charge transfer consideration. In addition, several aspects that are mutually important in this context will be outlined, namely, interlayer excitons, interfacial engineering, quantum confinement effect, and light–matter interactions. Based on these fundamental approaches, we translate the current understanding by highlighting several representative heterostructures with prominent performance such as light-emitting diodes, x-ray detectors, photodetectors, and solar cells. In this review, we focus on the rich chemistry and photophysics of these heterostructures, emphasizing the open questions related to their structure–property relationship.
