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.
