- Stimuli-responsive transmembrane anion transport by AIE-active fluorescent probes
-
Anticancer drug resistance implicates multifunctional mechanisms, and hypoxia is one of the key factors in therapeutic resistance. Hypoxia-specific therapy is considered an extremely effective strategy to fight against cancer. The development of small molecule-based synthetic anion transporters has also recently drawn attention for their potential therapeutic applications against several ion-transport-associated diseases, such as cancer and others. Herein, we describe the development of a hypoxia-responsive proanionophore to trigger controlled transport of anions across membranes under pathogenic conditions. Herein, we report the development of tetraphenylethene (TPE)-based anion transporters. The sulfonium-linkedp-nitrobenzyl containing TPE-based proanionophore could be converted into a lipophilic fluorescent Cl?ion carrier in a hypoxic or reductive environment. Stimuli such as nitroreductase (NTR) and glutathione (GSH) mediated regeneration of the TPE-based active Cl?ion transporter also showed aggregation-induced emission (AIE) properties. We hypothesize that such hypoxia and reductive stimuli activatable proanionophores have tremendous potential to fight against channelopathies, including cancer.

- Single-molecule conductance in a unique cross-conjugated tetra(aminoaryl)ethene
-
A 1,1,2,2-tetrakis(4-aminophenyl)ethene with three paths of π-conjugation, linear-cis, linear-trans and a cross-conjugation, has been prepared. The molecule is able to bind to gold electrodes forming molecular junctions for single-molecule conductance measurements. Only two regimes of conduction are found experimentally. The modelling of the conductance allows to assign them to through-bond transmission in the linear case, while the cross-conjugated channel is further assisted by through-space transmission, partially alleviating the destructive quantum interference.

A dissipative aggregation-induced emission (DAIE) system is successfully fabricated by coupling a stimuli-responsive AIE luminogens (AIEgens) with a pH oscillator. The novel DAIE system exhibits reversible, autonomous and sustainable AIE behaviour. Moreover, the DAIE behaviour can be regulated with the system temperature. The novel strategy will boost the development of bioinspired intelligent systems for real-world applications. This journal is

- Exploitation of two-dimensional conjugated covalent organic frameworks based on tetraphenylethylene with bicarbazole and pyrene units and applications in perovskite solar cells
-
In this work, two-dimensional conjugated covalent organic frameworks (2D-COF) based on a building block of tetraphenylethylene are successfully developed. Bicarbazole and pyrene moieties are respectively coupled with 4,4′,4′′,4′′′-(ethane-1,1,2,2-tetrayl)tetranilino (ETTA)via[4 + 4] solvothermal condensation conditions of 3,3′,6,6′-tetraformyl-9,9′-bicarbazole (Car-4CHO) and 1,3,6,8-tetrakis(4-formylphenyl)pyrene (TFPPy) to affordCar-ETTAandTFPPy-ETTACOFs. According to thermogravimetric analysis (TGA), powder X-ray diffraction (PXRD), and N2adsorption and desorption measurements, bothCar-ETTAandTFPPy-ETTACOFs exhibit excellent thermal stability, highly crystalline structure, and high specific surface area, respectively. These findings are supported by force field andab initiocalculations. Furthermore, successful applications of these COFs in perovskite solar cells (PVSCs) are demonstrated owing to their well-conjugated properties and π-π interactions. While serving as interlayers in the devices, these COFs could effectively promote the interfacial charge dynamic to further optimize the resulting performance. Besides, certain interaction between COFs and perovskite also leads to an improved morphology and crystallinity of the perovskite layer, presenting defect passivation capability. As a result, we show that the performance of the COF-modified PVSC could be improved from 17.40 to 19.80%.

- Oriented Films of Conjugated 2D Covalent Organic Frameworks as Photocathodes for Water Splitting
-
Light-driven water electrolysis at a semiconductor surface is a promising way to generate hydrogen from sustainable energy sources, but its efficiency is limited by the performance of available photoabsorbers. Here we report the first time investigation of covalent organic frameworks (COFs) as a new class of photoelectrodes. The presented 2D-COF structure is assembled from aromatic amine-functionalized tetraphenylethylene and thiophene-based dialdehyde building blocks to form conjugated polyimine sheets, which π-stack in the third dimension to create photoactive porous frameworks. Highly oriented COF films absorb light in the visible range to generate photoexcited electrons that diffuse to the surface and are transferred to the electrolyte, resulting in proton reduction and hydrogen evolution. The observed photoelectrochemical activity of the 2D-COF films and their photocorrosion stability in water pave the way for a novel class of photoabsorber materials with versatile optical and electronic properties that are tunable through the selection of appropriate building blocks and their three-dimensional stacking.

A crystalline microporous hydrogen-bonded cross-linked organic framework has been developed through covalent photo-cross-linking of molecular monomers that are assembled in a crystalline state. The elastic framework expands its void space to adsorb iodine rapidly with a high uptake capacity in an aqueous environment as well as recovering its crystalline form after the release of iodine.
