Organic semiconductor nanoparticles are expected to be used in organic optical and electronic devices due to their unique optical and electrical properties. However, no method has been reported for the preparation of high-quality organic nanoparticle films without remaining additives and being capable of dealing with binary nanoparticle blends. We developed a simple approach to fabricate high-quality organic semiconductor nanoparticle films from their aqueous solutions by solvent-evaporation-induced self-assembly. Only volatile solvents are employed in the nanoparticle solutions, so the self-assembled nanoparticle films are free of additives. Moreover, this method is also suitable for fabricating thin films containing binary nanoparticles. Therefore, it paves the way for potential applications of organic semiconductor nanoparticles in nanoscale optical and electronic devices.
有机半导体纳米粒子由于其独特的光学和电学性质，有望应用于有机光电子器件。然而，目前还没有报道制备高质量的有机纳米粒子薄膜的方法，这些薄膜不含残留添加剂，并且能够处理二元纳米粒子混合物。我们开发了一种简单的方法，通过溶剂挥发诱导自组装，从其水溶液中制备高质量的有机半导体纳米粒子薄膜。纳米粒子溶液中只使用挥发性溶剂，因此自组装的纳米粒子薄膜不含添加剂。此外，该方法也适用于制备含有二元纳米粒子的薄膜。因此，它为有机半导体纳米粒子在纳米尺度光电子器件中的潜在应用铺平了道路。
