Ionic liquids function as a nanosynthetic template for a "ligand-free" stepwise formation of gold nanoparticles (Au-NPs) which can be stopped and resumed at different color steps and Au-NP sizes (between 2.6 and 200 nm median diameter) and which can be reasoned by the DFT-calculation stabilization order: H(2)O (no Au-NP stabilization) < IL anion, e.g. BF(4)(-) approximately = PH(3) < citrate <Cl(-) (which inhibits Au-NP growth).
离子液体可作为纳米合成模板，实现“无配体”的金纳米粒子（Au-NPs）的逐步形成，可在不同颜色阶段和 Au-NP 尺寸（中值直径在 2.6nm 至 200nm 之间）之间停止和恢复，这可以通过 DFT 计算的稳定顺序来解释：H(2)O（不稳定 Au-NP）<离子液体阴离子，例如 BF(4)(-)≈ PH(3)<柠檬酸根<Cl(-)（其抑制 Au-NP 生长）。
