Dye-sensitized solar cells (DSSCs) have shown significant potential for indoor and building-integrated photovoltaic applications. Herein we present three new D-A-A organic sensitizers, XY1, XY2, and XY3, that exhibit high molar extinction coefficients and a broad absorption range. Molecular modifications of these dyes, featuring a benzothiadiazole (BTZ) auxiliary acceptor, were achieved by introducing a thiophene heterocycle as well as by shifting the position of BTZ on the conjugated bridge. The ensuing high molar absorption coefficients enabled the fabrication of highly efficient thin-film solid-state DSSCs with only 1.3 μm mesoporous TiO2 layer. XY2 with a molar extinction coefficient of 6.66 × 104 M-1 cm-1 at 578 nm led to the best photovoltaic performance of 7.51%.

The chemical structures or positive charge-guided specific cell organelles' staining was an interesting but very challenging research work. In this paper, we synthesized a series of triphenylamine (TPA) derivatives with mono-, di- and tri-pyridinium as su

Three triphenylamine (TPA) derivatives, constructed by the introduction of halogen atoms in TPA, show strong mechanoluminescence emissions, partially due to their various electronic configurations by virtue of the electron withdrawing ability of halogen atoms. Careful investigation of their single crystals and the density functional theory (DFT) calculations based on the crystal structure demonstrate that the enhanced intermolecular interactions and the twisted molecular structure contribute to their strong ML emission.
