Highlights The synthetic strategies and fundamental mechanisms of various asymmetric carbon- and silica-based nanomaterials were systematically summarized. The advantages of asymmetric structure on their related applications were clarified by some representative applications of asymmetric carbon- and silica-based nanomaterials. The future development prospects and challenges of asymmetric carbon- and silica-based nanomaterials were proposed. Abstract Carbon- and silica-based nanomaterials possess a set of merits including large surface area, good structural stability, diversified morphology, adjustable structure, and biocompatibility. These outstanding features make them widely applied in different fields. However, limited by the surface free energy effect, the current studies mainly focus on the symmetric structures, such as nanospheres, nanoflowers, nanowires, nanosheets, and core–shell structured composites. By comparison, the asymmetric structure with ingenious adjustability not only exhibits a larger effective surface area accompanied with more active sites, but also enables each component to work independently or corporately to harness their own merits, thus showing the unusual performances in some specific applications. The current review mainly focuses on the recent progress of design principles and synthesis methods of asymmetric carbon- and silica-based nanomaterials, and their applications in energy storage, catalysis, and biomedicine. Particularly, we provide some deep insights into their unique advantages in related fields from the perspective of materials’ structure–performance relationship. Furthermore, the challenges and development prospects on the synthesis and applications of asymmetric carbon- and silica-based nanomaterials are also presented and highlighted.

Recent research has indicated that fluorescent probes have tremendous potential for the selective detection of chemical and biological species. Over the past decade, researchers have proposed a series of fluorescence‐based sensing mechanisms of such probes by the calculation of their electronic excited states. Investigations of sensing mechanisms have been based on deep insights into the interactions between probe molecules and their target species, as well as their fluorescence properties. Advances in calculation methods, modeling software, and computational power have enabled researchers to use excited‐state theoretical calculations to reproduce experimental fluorescence phenomena and then provide molecular‐level explanations thereof. In this advanced review, we describe the evolution of theoretical studies on excited‐state sensing mechanisms for fluorescent probes that respond to target species. Focusing on calculation methods that facilitate investigation of the photophysical properties and excited‐state dynamics of probes, we emphasize sensing mechanisms mainly reported by our group. Most of these studies have been supported by theoretical predictions based on time‐dependent density functional theory. For this most popular excited‐state calculation method, vertical excitation energy, excited‐state geometrical optimization and a scan of the excited‐state potential energy surface should be noted in the calculation of electronic and molecular differences between the excited‐state probe and its reaction product with the target analyte. These state‐of‐the‐art calculations are of great importance for unraveling details of fluorescence‐based sensing mechanisms, including photochemical reactions (such as twist intramolecular charge transfer and excited‐state proton transfer) and excited‐state electronic processes (such as intramolecular charge transfer and photoinduced electron transfer). These studies have generated new and inspirational mechanistic proposals and have provided a systematic approach for the development of efficient fluorescent sensors.

“…Herein we report the design and synthesis of new TPA molecules decorated with the carboxylic acid group(s) for the detection of NACs through fluorescence sensing. Often fluorescent pH probes pertaining to the availability of H + are of greater significance due to various advantages such as non-destructive character, high sensitivity, and specificity 22 , 31 . It is essential to design the fluorescent sensors which would easily display fluorescence enhancements, high sensitivity, and selectivity towards the analyte molecule, which inspired us to use the potential –COOH functional groups as they can be easily converted to other activating receptors by forming a PET system 21 , 32 .…”

Detection of nitroaromatics employing greener techniques has been one of the most active research fields in chemistry. A series of triphenylamine (TPA) functionalized carboxylic acids were synthesized and characterized using various spectroscopic techniques including single-crystal X-ray diffraction analysis. The interaction of carboxylic acid-decorated TPAs with nitroaromatic compounds was photophysically explored using absorption and emission spectroscopy. Stern–Volmer plot accounts for the appreciable quenching constant of the TPA-acids. Density functional theory calculations were carried out to study the new compounds' frontier molecular orbital energy levels and the possible interactions with picrate anion and revealed an unusual charge transfer interaction between acids and picrate anion. The contact mode detection shows the TPA-acids can be used as dip-strip sensors for picric acid detection.
