Herein, a N-rich metal-organic framework (MOF) with four kinds of cages, Zn(ade)(TCA)(HO) (, Hade = adenine, HTCA = 4,4',4″-tricarboxytriphenylamine, NENU = Northeast Normal University), was prepared by the mixed-ligand strategy. Cationic dyes can be selectively absorbed by at proper concentrations, but not neutral and anionic dyes, which perhaps can be assigned to the N-rich neutral framework of . When was introduced to a relatively lower concentration of cationic dye solutions (e.g., rhodamine B or basic red 2), the colors of these systems faded quickly. Furthermore, the faded solutions can be used for the detection of methanol and other small alcohol molecules with either the naked eye or common UV-vis spectra. The effect of the length of carbon chain, the position of the -OH group, and the number of the hydroxyl group of the alcohols was explored for the color development rate. In addition, the performance of in iodine sorption and release was also studied.
在此，通过混合配体策略制备了一种具有四种笼结构的富氮金属-有机骨架（MOF），记为 Zn(ade)(TCA)(HO)（, Hade = 腺嘌呤，HTCA = 4,4',4″-三羧基三苯胺，NENU = 东北师范大学）。在适当浓度下，阳离子染料可以被 选择性地吸收，但中性和阴离子染料不能被吸收，这可能归因于 的富氮中性骨架。当 将引入到相对较低浓度的阳离子染料溶液（例如，罗丹明 B 或碱性红 2）中时，这些体系的颜色迅速褪去。此外，褪色溶液可以通过肉眼或常见的紫外可见光谱用于甲醇和其他小醇类分子的检测。探索了醇的碳链长度、-OH 基团的位置和羟基数量对显色速率的影响。此外，还研究了 在碘吸附和释放方面的性能。
