Article
Full-text available
Developing cost-effective, high-efficiency, and stable hole transporting materials (HTMs) is crucial for replacing traditional spiro-OMeTAD in perovskite solar cells (PSCs) and achieving sustainable solar energy solutions. This work presents two novel air-stable HTMs based on a spiro[fluorene-9,9′-xanthene] (SFX) core functionalized with N-methylca...
Article
A novel bis-BODIPY-based colorimetric and fluorescent sensor (BODIPY-NN) for F⁻ and CN⁻recognition with high selectivity and high sensitivity is reported. The designed sensor, BODIPY-NN, was synthesized by a one-step click reaction of azido-BODIPY with N,N′-dipropargylbenzene-1,2-diamine. The BODIPY-NN sensor displays a marked color change from pin...

A series of heteroditopic receptors containing halogen bond (XB) and unprecedented chalcogen bond (ChB) donors integrated into a 3,5‐bis‐triazole pyridine structure covalently linked to benzo‐15‐crown‐5 ether motifs exhibit remarkable cooperative recognition of halide anions. Multi‐nuclear ¹H, ¹³C, ¹²⁵Te and ¹⁹F NMR, ion pair binding investigations...

Halogen bond and chalcogen bond ion‐pair heteroditopic receptors exhibit remarkable cooperative recognition of halide anions via sodium cation–benzo‐crown ether binding. The chalcogen bonding receptor displays the largest enhancement of halide binding strength of over two hundred‐fold. DFT calculations suggest sodium cation crown ether complexation...
Article
A series of four new asymmetric di-anchoring dyes is reported, containing identical π spacer, acceptor, phenothiazine (PTZ) and arylamine (ArnN) moieties in the donor part but different bridging moieties (L): N–C bond, C–C bond, phenylamine and triphenylamine. Spectral, electrochemical, and photovoltaic experiments and density functional theory cal...
Article
This work presents an approach for designing efficient multi-anchoring dyes for dye-sensitized solar cells by using additional donor as a bridging group between donor–acceptor (D–A) side arms. With triarylamine as the additional donor and phenothiazine-cyanoacrylic acid as the D–A side arm, the multi-anchoring dyes exhibited higher molar extinction...
Article
The synthesis, photophysical and electrochemical properties, and photovoltaic performances in dye-sensitized solar cells (DSSCs) of five new metal-free organic sensitizers with a carbazole moiety as the electron donor are reported. The compounds contain a thiophene at various positions and a cyanoacrylic acid unit as the electron acceptor. The posi...
Article
A di-anchoring organic dye based on an acceptor–π spacer–donor–secondary donor–donor–π spacer–acceptor structural motif has been synthesized and used as a sensitizer for dye-sensitized solar cells (DSSCs). The new synthetic approach uses two π spacers, two acceptors and two different donors such as arylamino and carbazole units. The double donor–ac...
