In this work, Langmuir-Blodgett (LB) composite thin films were successfully prepared using black phosphorus nanosheets (BPNS) and dye molecules. Black phosphorus (BP) was first exfoliated in isopropanol solution to form BPNS, and then, BPNS were modified with 4-azidobenzoic acid (Az-BPNS) to improve their stability. The characterization results showed that the synthesized Az-BPNS-dye LB films have a uniform and ordered structure. In addition, the synthesized Az-BPNS-dye LB films exhibit excellent photoelectrochemical performance, and Az-BPNS-methylene blue (MB) produces higher photocurrent compared to Az-BPNS-Neutral red (NR) films. The current work shows an effective way to prepare functionalized BP-based materials and provide evidence for their application in optoelectronic devices.
在这项工作中，成功地使用黑磷纳米片（BPNS）和染料分子制备了朗缪尔-布洛杰特（LB）复合薄膜。首先在异丙醇溶液中剥离黑磷（BP）以形成BPNS，然后用4-叠氮基苯甲酸（Az-BPNS）对BPNS进行改性以提高其稳定性。表征结果表明，合成的Az-BPNS-染料LB薄膜具有均匀且有序的结构。此外，合成的Az-BPNS-染料LB薄膜表现出优异的光电化学性能，与Az-BPNS-中性红（NR）薄膜相比，Az-BPNS-亚甲基蓝（MB）产生更高的光电流。当前的工作展示了一种制备功能化BP基材料的有效方法，并为其在光电器件中的应用提供了证据。
