分子太阳能热系统(MOST)通过可逆光异构化作用,将太阳能直接储存在光开关分子的化学键中,其中最突出的是降冰片二烯-四环烷对。入射光子驱动分子从稳定的基态跃迁到张力较高的态。 高能 价异构体可以储存能量——可能长达数月——直到催化触发引发逆反应,从而按需释放热量。
系统性能取决于量子产率、与太阳光谱匹配的摩尔消光系数、单分子能量密度、逆异构化活化能垒以及在重复循环中的长期抗疲劳性。通过取代基调控和共轭连接基团进行分子功能化、连续流动光反应器以及基于密度泛函理论(DFT)的设计,构成了当前的研究前沿。

The Integration of a Metal Active Site and Photosensitive Unit
Published on 2026-01-19 by Haoyue Sun, Yu Yang, Yanchang Liu, Dongxue Yang, Yichang Liu, Zaicheng Sun @MDPI
Abstract: Metallaphotoredox catalysis merges the powerful bond-forming abilities of transition metal catalysis with unique electron or energy transfer pathways accessible in photoexcited states, injecting new vitality into organic synthesis. However, most transition metal catalysts cannot be excited by visible light. Thus, prevalent metallaphotoredox catalytic systems require dual catalysts: a transition metal catalyst and a separate photosensitizer. This leads to inefficient electron transfer between the[...]

Abstract: Studying nanoscale self-assembly in real time using external stimuli unlocks new opportunities for dynamic and adaptive materials. While electrostatic self-assembly is well-established, real-time monitoring of its structural evolution under light irradiation remains largely unexploited. In this study, we employ light-responsive azobenzene dyes (Acid Yellow 38, AY38) and pH-sensitive polyamidoamine (PAMAM) dendrimers to investigate the kinetics of electrostatic self-assembly under UV irradiation.[...]
