Crystal melting and vitrification of nitrile-based two-dimensional coordination polymer (CP) were studied. The crystal melts at 169 °C and has a wide liquid-state temperature window of over 110 °C. The crystalline state transformed to a glassy state by melt-quench or mechanical milling. The mechanically induced glass showed permanent porosity, and it also showed glass-to-crystal transformation upon solvent treatment. Surface crystallization on top of the grain-boundary-free glass monolith was demonstrated.

2D腈基配位聚合物的稳定熔体形成和分层晶体玻璃结构。
研究了腈基二维配位聚合物（CP）的晶体熔融和玻璃化。晶体在169°C时熔化，并具有超过110°C的宽液态温度窗口。结晶态通过熔融淬火或机械研磨转变成玻璃态。机械诱导的玻璃显示出永久的孔隙率，并且在溶剂处理后还显示出玻璃到晶体的转变。证实了在无晶界的玻璃整体顶部上的表面结晶。
