Abstract
En 中文
While 2D metal-organic hybrids have emerged as promising solar absorbers due to their improved moisture stability, their inferior transport properties limit their potential translation into devices. We report a new hybrid containing 2-(2-ammonioethyl)pyridine [(2-AEP)(+)], forming a 2D hybrid with the composition (2-AEP)(2)PbI4. The organic bilayer comprises of (2-AEP)(+), which is arranged in a face-to-face stacking that promotes pi-pi interactions between neighboring pyridyl rings. We also demonstrate the structural diversity of 2-(2-aminoethyl)pyridine-based lead iodide hybrids in solution-processed films. This report highlights the importance of solution-processing conditions in trying to obtain single-phase films of hybrids containing dibasic organic species.
