MIL-140B 纳米晶压力增强反平行堆叠实现全可见光谱压致变色
Pressure‐Enhanced Antiparallel Stacking Enables Full‐Visible‐Spectrum Piezochromism in MIL‐140B Nanocrystals
AI 导读
MIL-140B 纳米晶在压缩过程中实现全可见光谱压致变色，光致发光红移达 212 nm，超过此前所有报道的 MOF 的 PL 范围。其有机配体 2,6-萘二甲酸（NDC）在常压下呈反平行 π–π 堆叠，降低了初始 π–π 共轭并提升 PL 效率；加压下 NDC 单元间 π–π 堆叠增强使带隙逐步收窄，从而实现全可见光谱压致变色。
