Thermo-responsive polymer-modified metal– organic frameworks as soft–rigid enzyme-reactors for enhancement of enzymolysis efficiency using a controllable embedding protocol

Juan Qiao,‡ Cheng Cheng,‡ Dan Li and Li Qi*Enzyme immobilization is a suitable strategy to promote biosensing, biocatalysis and the industrialapplications of biomacromolecules. Although considerable efforts have been devoted to the constructionof metal–organic frameworks (MOFs)-based porous nano-reactors, their enzymolysis efficiency cannot betuned by varying the external conditions due to the fixed conformation of the encapsulated enzymes. Inthis work, a controllable embedding protocol was deve

Acid-triggered interlayer sliding of twodimensional copper(I)–organic frameworks: more metal sites for catalysis

Hou-Gan Zhou, Ri-Qin Xia,a Ji Zheng, Daqiang Yuan, Guo-Hong Ning *and Dan Li *The interlay sliding of two-dimensional (2D) metal–organic and covalent–organic frameworks (MOFs and COFs) affects not only the layout features of the structures, but also the functional output of the materials.However, the control of interlay stacking is the major hurdle that needs to be overcome to construct new functional layer materials. Herein, we report the preparation of a pair of isostructural 2D copper(I) orga

Pressure-induced phosphorescence enhancement and piezochromism of a carbazole-based cyclic trinuclear Cu(I) complex

Mo Xie, Xiao-Ru Chen, Kun Wu, Zhou Lu, Kai Wang, Nan Li, Rong-Jia Wei, Shun-Ze Zhan, Guo-Hong Ning, * Bo Zou * and Dan Li *limited to pure organic compounds and fluorescence. In this work, a Cu3Pz3 (Cu3, Pz: pyrazolate) cyclic trinuclear complex (CTC) with two different crystalline polymorphs, namely 1a and 1b, was synthesized. The CTC consists of two functional moieties: carbazole (Cz) chromophore and Cu3 units. In crystals of 1a, discrete Cz–Cu3–Cu3–Cz stacking was found, showing abnormal pres

Aggregation-induced phosphorescence sensitization in two heptanuclear and decanuclear gold–silver sandwich clusters

Zhou Lu, Yu-Jie Yang, Wen-Xiu Ni, Mian Li, Yifang Zhao, Yong-Liang Huang, Dong Luo, Xiaoping Wang, Mohammad A. Omary * and Dan Li *The strategy of aggregation-induced emission enhancement (AIEE) has been proven to be efficient in wide areas and has recently been adopted in the field of metal nanoclusters. However, the relationship between atomically precise clusters and AIEE is still unclear. Herein, we have successfully obtained two few-atom heterometallic gold–silver hepta-/decanuclear cluster

Immobilizing Redox-Active Tricycloquinazoline into a 2D Conductive Metal–Organic Framework for Lithium Storage

Jie Yan, Yutao Cui, Mo Xie, Guo-Zhan Yang, De-Shan Bin,* and Dan Li*Abstract: Heteroaromatic-conjugated aromatic molecules have inspired numerous interests in rechargeable batteries like Li-ion batteries, but were limited by low conductivity and easy dissolution in electrolytes. Herein, we immobilize a nitrogen-rich aromatic molecule tricycloquinazoline (TQ) and CuO4 unit into a two-dimensional (2D) conductive metal–organic framework (MOF) to unlock their potential for Li+storage. TQ was identif

Turn-On Circularly Polarized Luminescence in Metal–Organic Frameworks

Turn-On Circularly Polarized Luminescence in Metal–Organic FrameworksXue-Zhi Wang, Meng-Ying Sun, Zhijin Huang, Mo Xie, Ruishan Huang, Huihui Lu, Zujin Zhao, Xiao-Ping Zhou,* and Dan Li**The fabrication of circularly polarized luminescence (CPL) active materials by self-assembly is still in its challenge. In this work, a family of homochiral metal–organic frameworks (MOFs) and metal–organic cages (MOCs) are constructed by solvothermal subcomponent self-assembly. These MOFs feature an eta topolog
