Abstract

New 2D black phosphorus (bP)-phthalocyanine (Pc) nanohybrids have been synthesized by liquid phase exfoliation of black phosphorus crystals in the presence of two organic dyes: phthalocyanine (Pc) and manganese phthalocyanine (MnPc). The key role of the metal cation in the interfacial interaction between the organic dye and bP nanosheets was demonstrated by X-ray absorption spectroscopy and associated with an electron transfer between the metal cation Mn and bP nanosheets, which resembles a coordinative chemical bond. On the other hand, the interaction between bP nanosheets and pure phthalocyanine is governed by van der Waals forces. The fluorescence of both hybrids is significantly reduced indicating effective separation of the photoinduced charge, implying the formation of a heterojunction between the organic molecules and the bP nanosheets. These findings provide important insights into the interfacial interactions in bP-Pc nanohybrids that are relevant for application in 2D organic/inorganic devices.

摘要

通过在两种有机染料（酞菁（Pc）和锰酞菁（MnPc））存在的情况下对黑磷晶体进行液相剥离，合成了新型二维黑磷（bP）-酞菁（Pc）纳米杂化物。通过X射线吸收光谱证明了金属阳离子在有机染料与bP纳米片之间的界面相互作用中的关键作用，该作用与金属阳离子Mn和bP纳米片之间的电子转移有关，这类似于配位化学键。另一方面，bP纳米片与纯酞菁之间的相互作用受范德华力支配。两种杂化物的荧光均显著降低，表明光生电荷有效分离，这意味着在有机分子与bP纳米片之间形成了异质结。这些发现为bP-Pc纳米杂化物中的界面相互作用提供了重要见解，这与二维有机/无机器件中的应用相关。
