By confining and concentrating light in a nanometric volume at the apex of a metallic tip, sub-molecule-scale control of a basic photochemical reaction — phototautomerization — is now shown to be possible. Applicable to other photo-induced reactions, this technique signals a new strategy for the synthesis of complex molecules on surfaces.

具有亚分子分辨率的光诱导化学

通过将光限制和集中在金属尖端顶点的纳米体积内，对基本光化学反应（光互变异构化）的亚分子尺度控制现在被证明是可能的。该技术适用于其他光诱导反应，标志着一种在表面合成复杂分子的新策略。
