双光子处理提供了一种在三维空间中调整材料特性的简便方法。通过多变量策略在金属有机骨架中加入光活性连接体，实现了双光子响应金属有机骨架（MOF）。得到的MOF在紫外光和红外飞秒激光的激发下表现出明显的单光子和双光子荧光变化，从而实现了MOF荧光特性的空间调制。从而证明了晶体内部双光子图像化和成像的能力，并形成了高分辨率的三维双光子激发荧光结构。
Two-photon processing presents a facile means to tailor the properties of materials in three-dimensions. A two-photon responsive metal-organic framework (MOF) has been realized through the incorporation of a photoactive linker into a MOF via a multivariate strategy. The resulting MOF exhibits a significant one-photon and two-photon excited fluorescence change in response to UV light and infrared femtosecond laser, enabling spatial modulation of the fluorescence property of the MOF. It thus demonstrates the capacity of two-photon patterning and imaging inside the crystal, and the formation of three-dimensional two-photon excited fluorescent structure in a high resolution.
