HOFs are assembled from organic building blocks through H-bonding interactions. The resultant framework can be further reinforced <em>via</em> weak connections such as π-π, van der Waals, and/or C-H-π interactions. The highly flexible and reversible HOF structures are exceptionally suitable for the realization of smart HOF materials. To this end, it is crucial to unravel and control the photobehavior of these compounds at intimate levels by the use of advanced laser-based spectroscopy and microscopy techniques. The use of light to study the photophysical processes of HOF-based systems will help to trigger further research to expand their applicability in the related fields. This Review surveys the past-10-years contributions on the spectroscopy and photoinduced fast/ultrafast dynamics of HOFs, the interactions between their building units, the effect of light on their photostability, and most important photonic applications. The aim of this work is to give a rich up-to-date summary of photochemistry and related applications of HOFs and their composites. The reviewed HOFs have been divided into different families based on the nature of the linker, with the purpose of offering to the reader a concise understanding of the related photoinduced processes within each family. The relevant applications of HOFs are also briefly summarized to validate their potential use in modern science and technology.</p></div>","PeriodicalId":376,"journal":{"name":"Journal of Photochemistry and Photobiology C: Photochemistry Reviews","volume":"47 ","pages":"Article 100418"},"PeriodicalIF":13.6,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.jphotochemrev.2021.100418","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"2606852","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}

Well into the 21 st century, scientists have not agreed on the mechanism of action, primary site, and roles of excess energy absorbed by photosynthetic pigments. It is recognized that Photosystem II is the most fragile component during photoinhibition and that excess excitation absorbed by the photosynthetic pigments has a strong impact on it. Consensus is yet to come on terminology, guidelines to study photoinhibition, or boundaries of what can be considered photodamage. Some of these controversies are the result of how we understand the phenomenon of photoinhibition, as this is what determines a given experimental design. Thus, how we understand photodamage depends on the philosophical approach of each group. While some efforts have been made in the parametrization of Photosystem II photoinhibition, an updated review about the concepts of photoinhibition of Photosystem II and how to study it is still pending. In this work, a review of the concepts used in the field of photoinhibition is presented, accompanied by a synopsis on the history and mechanisms of action.</p></div>","PeriodicalId":376,"journal":{"name":"Journal of Photochemistry and Photobiology C: Photochemistry Reviews","volume":"47 ","pages":"Article 100421"},"PeriodicalIF":13.6,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.jphotochemrev.2021.100421","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"2801384","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}

Here, strategies for the design and fabrication of nanocarriers for NIR light-controlled release are reviewed, which are based on three triggering mechanisms: (1) photoreactions of chromophores, including NIR light-induced photoreactions and upconversion nanoparticles (UCNPs)-mediated photochemical reactions; (2) photothermal effect, triggered by inorganic or organic photothermal conversion agents (PCAs) with the excitation of NIR light; (3) photo-oxidation, induced by reactive oxygen species (ROS) generated by photosensitizers under NIR light radiation. Finally, the challenges and perspectives of NIR light-sensitive nanocarriers for future development are given.</p></div>","PeriodicalId":376,"journal":{"name":"Journal of Photochemistry and Photobiology C: Photochemistry Reviews","volume":"47 ","pages":"Article 100420"},"PeriodicalIF":13.6,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.jphotochemrev.2021.100420","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"2801383","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}

However, it is hard to convert methane into more useful hydrocarbons and hydrogen due to the enormous thermodynamic barrier, which often needs high energy and often results in catalyst deactivation and unsatisfactory product selectivity. Recently, a growing number of researches focusing on photocatalytic methane conversion under mild conditions have attracted much attention, demonstrating that photocatalytic non-oxidative coupling of methane (PNOCM) is a prospective and green method for methane conversion under mild conditions. Herein, we provide a review of the recent advance, remaining challenges, and prospects in PNOCM. Moreover, this review provides considerable guidance for rational design of efficient and stable photocatalysts towards PNOCM by theory predictions and experiment results.
