膦引发的阳离子交换是众所周知的无机化学反应。在这项工作中，不同的膦被用来调节阳离子交换反应的热力学和动力学参数，以合成复杂的半导体纳米结构。除了保留原始形状和尺寸外，膦引发的阳离子交换反应还显示出精确调节金属/半导体核壳和掺杂纳米晶体的结晶度和成分的潜力。此外，还对不同的膦及其基元反应机理进行了系统研究。
Phosphine-initiated cation exchange is a well-known inorganic chemistry reaction. In this work, different phosphines have been used to modulate the thermodynamic and kinetic parameters of the cation exchange reaction to synthesize complex semiconductor nanostructures. Besides preserving the original shape and size, phosphine-initiated cation exchange reactions show potential to precisely tune the crystallinity and composition of metal/semiconductor core-shell and doped nanocrystals. Furthermore, systematic studies on different phosphines and on the elementary reaction mechanisms have been performed.
