Aiming at the construction of novel multistate circularly polarized luminescence(CPL) switches, dual stimuli-responsive chiral[2]rotaxanes towards anions and light have been designed and constructed. Through the light-controlled on/off F?rster resonance energy transfer(FRET) switching between the emissive stoppers and anion-induced controllable motions of the chiral wheel for the precise regulations of chirality information transfer from the chiral wheel to the emissive stoppers, precisely switching between four CPL emission states with varied emission wavelengths and dissymmetry factors has been successfully realized,making them a promising platform for practical uses such as information storage and encryption. This proof-of-concept study not only provides a novel design strategy for multistate CPL switching but also contributes excellent candidates for the construction of novel smart chiral luminescent materials.

Supercapacitors(SCs) have remarkable energy storage capabilities and have garnered considerable interest due to their superior power densities and ultra-long cycling characteristics. However, their comparatively low energy density limits their extensive application in large-scale commercial applications. Electrode materials directly affect the performance of SCs. Thus, the development of cutting-edge electrode materials and modification of their morphological and structural properties are vital for advancing the performance of SCs. Transition metal compounds have a high specific capacity and good cycling durability, making them the most promising electrode active materials for high-energy density SCs. Nevertheless,their inadequate conductivity, unfavorable ion diffusion rates, substantial volume expansion and phase transitions during charging and discharging are obstacles to their stable and efficient integration into SCs. To address these challenges, this study provides a comprehensive summary of the current advancements in transition metal nanomaterials as electrode materials for SCs, an overview of the current research status, and the prevailing ***, this study highlights synthetic techniques and management strategies for electrode materials derived from transition metal compounds, targeting the resolution of the aforementioned challenges. Finally, a concise discussion is provided on the future directions of SC development, with an emphasis on the utilization of transition metal compound electrode materials.

郑杭生先生是最早认识到韦伯研究的重要性并对韦伯社会学思想进行深入研究的中国内地学者之一。他坚持借鉴国外、创造特色的理论自觉,对韦伯的社会学思想加以深入研究和借鉴应用。他在对韦伯“价值中立”思想的系统阐释中确立了中国特色马克思主义社会学的正确方向,在建构社会运行论、社会转型论、社会互构论等中国特色社会学理论的过程中,不同程度上受到韦伯“理想类型”等思想的启发与影响。在与韦伯“传统—现代”分析框架对话的基础上,他创造性地提出了新时期“社会共同性”“新型现代性”“新型社会主义”等概念和命题。郑杭生先生以高度的理论自觉对韦伯研究的重视和对韦伯思想的借鉴应用,对新时代中国特色社会学知识体系的建设仍有重要启迪意义。
