The rational design and engineering of metal–organic framework (MOF) crystals with hollow features has been used for various applications. Here, a top‐down strategy is established to construct hollow MOFs via synergistic etching and surface functionalization by using phenolic acid. The macrosized cavities are created inside various types of MOFs without destroying the parent crystalline framework, as evidenced by electron microscopy and X‐ray diffraction. The modified MOFs are simultaneously coated by metal–phenolic films. This coating endows the MOFs with the additional functionality of responding to near infrared irradiation to produce heat for potential photothermal therapy applications.

通过协同蚀刻和表面功能化实现金属有机框架中的空隙工程

具有中空特征的金属有机框架(MOF)晶体的合理设计和工程已用于各种应用。在这里,建立了一种自上而下的策略,以通过使用酚酸的协同蚀刻和表面功能化来构造空心MOF。电子显微镜和X射线衍射证明,在各种类型的MOF内均会形成宏观的空腔,而不会破坏母体的晶体框架。改性的MOF同时涂有金属酚醛薄膜。该涂层赋予MOF额外的功能,使其能够响应近红外辐射而产生热量,以用于潜在的光热疗法应用。
