Two isostructural pillar-layer MOFs (JNU-105 and JNU-105-(NH2)2) have been successfully synthesized. JNU-105-(NH2)2 exhibits a red-shifted luminescence "turn on" for formaldehyde without the interference from other VOCs and a detection limit of 1.87 ppb. single-crystal transformation studies confirm the aminal formation on the pillar linker, which was attributed to the exclusive luminescence response toward formaldehyde.
两种同构的柱状层 MOF（JNU-105 和 JNU-105-（NH2）2）已成功合成。JNU-105-（NH2）2 对甲醛表现出红移发光“开启”，不受其他 VOC 的干扰，检测限低至 1.87 ppb。单晶转变研究证实了支柱连接体上亚胺的形成，这归因于对甲醛的独特发光响应。
