A Novel Amine-Free Dianchoring Organic Dye for Efficient Dye-Sensitized Solar Cells
摘要:
An amine-free oligothiophene-based dye (BTB) featuring a tailor-made dianchoring function, a spiro-configured central unit, and bulky end-capping TIPS groups to diminish intermolecular interactions and to suppress aggregation-induced self-quenching was synthesized to achieve efficient dye-sensitized solar cells with a high power conversion efficiency of 6.52%.

A new, highly adaptable type of phosphinamide-based hydrogen bonding is representatively demonstrated in π-conjugated phosphole materials. The rotational flexibility of these intermolecular P=O-H-N hydrogen bonds is demonstrated by X-ray crystallography and variable-concentration NMR spectroscopy. In addition to crystallinecompounds, phosphinamide hydrogen bonding was successfully introduced into
