Molecular chirality transfer and amplification is at the heart of the fundamental understanding of chiral origin and fabrication of artificial chiral materials. We investigate here the nonlinear amplification effect in the chiral transfer from small molecules to assembled plasmonic nanoparticles. Our results show clearly a recognizable nonlinear behavior of the electronic and plasmonic circular dichroism activities, demonstrating the validity of the “majority-rules” principle operating in both the three-dimensional interface-confined molecularly chiral environment and the assembled plasmonic nanoparticles. Such twin “majority-rules” effects from the self-assembled organic–inorganic nanocomposite system have not been reported previously. By establishing a direct correlation between the dynamic template of the molecularly chiral environment and the nonlinear chiral amplification in the nanoparticle assemblies, this study may provide an insightful understanding of the hierarchical and cooperative chiral information transfer from molecular levels to nanoscales.

自组装等离子体纳米结构中手性的非线性放大

分子手性的转移和扩增是对手性起源和人工手性材料制造的基本理解的核心。我们在这里研究从小分子到组装的等离激元纳米粒子的手性转移中的非线性放大效应。我们的结果清楚地表明了可识别的电子和等离子体圆二色性行为的非线性行为，证明了在三维界面受限的分子手性环境和组装的等离子体纳米颗粒中运行的“多数规则”原理的有效性。自组装有机-无机纳米复合材料系统产生的这种双重“多数规则”效应以前尚未见报道。
