The creation and control of two-dimensional superconductivity in clean systems are crucial for investigating quantum phase transitions and emergent phenomena. Here, the authors achieve robust 2D superconductivity on a bulk organic Mott insulator using a photochromic spiropyran derivative, enabling light-driven carrier injection and access to exotic quantum critical phenomena via a versatile, non-invasive platform to manipulate 2D states on clean bulk crystals.
