A molecular dual pump / Yunyan Qiu
Publications – 1172
A molecular dual pump, which consists of two individual pumps linked in a head-to-tail fashion, has been designed and synthesized for the controlled capture and release of a ring via a rotaxane intermediate.
Conductive 2D MOFs for Zinc Batteries / Kwan Woo Nam
Publications – 1170
A redox-active triangular phenanthrenequinone-based macrocycle (PQ-Δ) with a rigid geometry has been developed as a zinc battery cathode. The macrocyclic nature of the PQ-Δ cathode provides a dramatically increased capacity and cyclability compared to that of traditional organic materials.
Cyclophane-Protected NDI Radical / Kang Cai
Publications – 1169
A new strategy has been presented which stabilizes the NDI•– radical anion and modulates its redox properties, by host-guest encapsulation and/or mechanical interlocking with a tetracationic cyclophane, namely, ExBox4+.
Artificial Allomelanin Nanoparticles / Yuanning Feng
In Collaboration with – Gianneschi Group / Xuhao Zhou
Publications – 1168
Artificial allomelanin nanoparticles (AMNPs), analogous to one type of melanin produced by radiation-resistant fungi, have been prepared with well-defined nanostructures. They can be taken up by human epidermal keratinocytes and act as radical scavengers.
A Supramolecular Diamond / Qinghui Guo
Publications – 1167
A unique approach has been established for constructing supramolecular diamond crystals with nanoporous diamondoid superstructures and octahedral shapes, resulting from the hierarchical self-assembly of preorganized hexa-charged molecules quantitatively within seconds under ambient conditions.
Supramolecular Polyknot / Penghao Li
Publications – 1166
A hydrogen-bonded three-dimensional porous supramolecular polyknot with unprecedented self-entangled topology is assembled from a rigid trigonal prismatic triptycene building block with six extended peripheral aryl-carboxyl groups.
Cyclotris(paraquat-p-phenylenes) / Qinghui Guo
Publications – 1165
Redox-active and shape-persistent cyclophanes, namely CTPQT6+ and MCTPQT6+, which are the homologous tricyclic derivatives of the trademark Blue Box from our group, have been synthesized. These derivatives adopt triangular conformations and the 3D packing of MCTPQT6+ results in nanometer-sized channels in the solid state.
Regulated Photodynamic Activity of a Photosensitizer / Indranil Roy
Publications – 1164
A multifunctional synthetic receptor ExBox4+ has been employed to achieve supramolecular photoprotection, lysosomal delivery, and pH-triggered release of a photosensitizer. The use of the ExBox4+ -bound photosensitizer in anticancer treatment using regulated photodynamic therapy is described.
Ligand-Directed Synthesis of Zr-MOFs / Penghao Li
In Collaboration with – Farha Group / Zhijie Chen
Publications – 1163
A series of zirconium-based metal-organic frameworks (Zr-MOFs), i.e. NU160X, with the edge-transitive alb net, was synthesized reticularly from 12-connected hexagonal Zr6 nodes and 6-connected trigonal-prismatic triptycene linkers. These Zr-MOFs exhibit remarkable activities toward the destruction of a nerve agent (Soman) and a nerve agent simulant.
In Situ Photoconversion of Multicolor Luminescence / Huang Wu
Publications – 1160
A photoluminescent supramolecular assembly, the fluorescence of which can be changed efficiently from yellow to blue in an in situ photo-controlled manner, has been prepared in two stages. Employing this assembly, white light emission can be realized expeditiously by a luminescence color-conversion process.
Highly Porous acs-MOFs for Water Sorption / Penghao Li
In Collaboration with – Farha Group / Zhijie Chen
Publications – 1158
A series of non-catenated metal-organic frameworks based on the acs net (acs-MOFs), i.e. NU-1500, was synthesized from trivalent trinuclear metal (Fe3+, Cr3+ and Sc3+) clusters and 6-connected trigonal-prismatic linkers. The highly porous and hydrolytically stable NU-1500-Cr can be activated directly from water and displays an impressive water vapor uptake with a trace of hysteresis.
Interpenetration Isomerism in HOFs / Penghao Li
Publications – 1157
A trigonal prismatic triptycene building block assembles into either a two‐fold interpenetrated acs network (acs‐2 c) or a five‐fold interpenetrated acs network (acs‐5 c) depending upon the crystallization conditions.
Controllable Molecular Encapsulation with Dynamic Host / Huang Wu
Publications – 1156
When a photo-switchable oligo(p-phenylenevinylene) bipyridinium unit (light pink) is incorporated into a tetracationic cyclophane (light blue), it confers upon the cyclophane the ability to direct reversible guest (red and pink) capture and release using thermal and photo stimuli.
Cyclophane for Live-Cell Imaging / Indranil Roy
Publications – 1141
A glowing tetracationic cyclophane (ExTzBox•4Cl) with unity quantum yield has been synthesized and utilized for live-cell imaging. This work, which describes the significance of using box-like cyclophanes for bioimaging, holds promise for the development of multimodal imaging platforms.
