金属配位化合物（MCC）玻璃[例如，金属-有机框架（MOF）玻璃、配位聚合物玻璃和金属无机-有机络合物（MIOC）玻璃]是混合玻璃家族的新兴成员。到目前为止，有限数量的结晶MCC可以通过熔融淬火转化为玻璃。在这里，我们报告了一种通用的湿化学方法，通过该方法可以从不可熔的MOFs合成超大尺寸的超分子MIOC玻璃。用酸和醇作为抑制剂。MIOC玻璃具有独特的功能，包括高透明度、成形能力和各向异性网络。在掺杂有机染料的样品中观察到了具有大偏振比（~ 47%）的定向光致发光.这种结晶抑制方法能够制造超大尺寸的MCC玻璃，这是传统玻璃化方法无法实现的，因此可以探索具有光子功能的新MCC玻璃。
Metal coordination compound (MCC) glasses [e.g., metal‐organic framework (MOF) glass, coordination polymer glass, and metal inorganic‐organic complex (MIOC) glass] are emerging members of the hybrid glass family. So far, a limited number of crystalline MCCs can be converted into glasses by melt‐quenching. Here, we report a universal wet‐chemistry method, by which the super‐sized supramolecular MIOC glasses can be synthesized from non‐meltable MOFs. Alcohol and acid were used as agents to inhibit crystallization. The MIOC glasses demonstrate unique features including high transparency, shaping capability, and anisotropic network. Directional photoluminescence with a large polarization ratio (≈47 %) was observed from samples doped with organic dyes. This crystallization‐suppressing approach enables fabrication of super‐sized MCC glasses, which cannot be achieved by conventional vitrification methods, and thus allows for exploring new MCC glasses possessing photonic functionalities.
