Three-in-One: Molecular Engineering of D-A-π-A Featured Type I and Type II Near-Infrared AIE Photosensitizers for Efficient Photodynamic Cancer Therapy and Bacteria Killing.

Bacterial infections are closely correlated with the genesis and progression of cancer, and the elimination of cancer-related bacteria may improve the efficacy of cancer treatment. However, the combinatorial therapy that utilizes two or more chemodrugs will increase potential adverse effects. Image-guided photodynamic therapy is a highly precise and potential therapy to treat tumor and microbial infections.

An ethyl thioglycolate-based chemosensor: Spectrophotometric detection of Fe and fluorometric detection of Hg with high selectivity.

A novel symmetric bianthracene derivative (D2) containing one benzene ring and two ethyl thioglycolates connecting to the benzene ring on both sides of the bianthracene unit was designed and synthesized. D2 can detect Fe and Hg in acetonitrile/water (6:4, v/v) solution via different changes of absorbance and fluorescence in the pH range from 3 to 10. D2 exhibits high colorimetric sensitivity for Fe with low detection limit (1.

Simultaneous Interphase Optimizations on the Large-Area Anode and Cathode of High-Energy-Density Lithium-Ion Pouch Cells by a Multiple Additives Strategy.

Prior to the maturation of next-generation energy storage devices, the actual lithium-ion batteries for commercial purposes are still expected to fulfill some critical requirements, among which the high energy density, wide operating temperature range, and related long-term cycling stability are the most challenging issues. Herein a multiple additives strategy is employed to simultaneously optimize the solid electrolyte interphase on the large-area anode and cathode in a 2 Ah artificial graphite (AGr)/LiNiCoMnO (NCM523) pouch cell with high gravimetric (>260 Wh kg) and volumetric (>630 Wh L) energy density. By introducing a rational mixture of electrolyte additives, a highly sulfurized surface layer and a uniform and thin passivation layer are separately formed on the anode and cathode of the AGr/NCM523 pouch cell, exhibiting high storage stability at 60 °C, much improved discharge capacity at -10 and -20 °C, high anodic stability at high voltage of 4.

A simple indolo[2,3-a]carbazole based colorimetric chemosensor for simultaneous detection of Cu and Fe ions.

A new indolo[2,3-a]carbazole based colorimetric chemosensor C1 was designed and synthesized. The optical properties of C1 were investigated by UV-vis spectroscopy, UV-vis titrations, and fluorescence spectroscopy. The HOMO and LUMO values of C1 were obtained using density functional theory (DFT) calculations.

2,3-Dipentyldithieno[3,2-f:2',3'-h]quinoxaline-Based Organic Dyes for Efficient Dye-Sensitized Solar Cells: Effect of π-Bridges and Electron Donors on Solar Cell Performance.

Five novel metal-free organic dyes DQ1-5 containing a dipentyldithieno[3,2-f:2',3'-h]quinoxaline (DPQ) unit were synthesized and applied in dye-sensitized solar cells (DSSCs), where DPQ was employed as a π-spacer for the first time. Their photophysical, electrochemical, and theoretical calculations and photovoltaic properties were systematically investigated. All the five dyes show broad photoresponse.
