Using IR spectroscopy, high‐pressure reactions of molecules were observed in liquids entrapped by graphene nanobubbles formed at the graphene–diamond interface. Nanobubbles formed on graphene as a result of thermally induced bonding of its edges with diamond are highly impermeable, thus providing a good sealing of solvents within. Owing to the optical transparency of graphene and diamond, high‐pressure chemical reactions within the bubbles can be probed with vibrational spectroscopy. By monitoring the conformational changes of pressure‐sensitive molecules, the pressure within the nanobubble can be calibrated as a function of temperature and it is about 1 GPa at 600 K. The polymerization of buckministerfullerene (C₆₀), which is symmetrically forbidden under ambient conditions, is observed to proceed in well‐defined stages in the pressurized nanobubbles.

观察石墨烯气泡中的高压化学

使用红外光谱，在石墨烯-金刚石界面处形成的石墨烯纳米气泡截留的液体中观察到分子的高压反应。由于石墨烯的边缘与金刚石发生热诱导键合而在石墨烯上形成的纳米气泡是高度不渗透的，因此可以很好地密封其中的溶剂。由于石墨烯和金刚石的光学透明性，气泡中的高压化学反​​应可以通过振动光谱法进行探测。通过监测压敏分子的构象变化，可以将纳米气泡内的压力作为温度的函数进行校准，并且在600 K下约为1 GPa。buckministerfullerene（C ₆₀）（在环境条件下被对称禁止）被观察到在加压的纳米气泡中以明确的阶段进行。
