Abstract

A cucurbit[6]uril (CB[6]) based supramolecular assembly CB[6]-[NDS] (1, NDS = 2,6-naphthalenedisulfonic acid anion) was used to detect dyes such as reactive blue 19 (RB19), rhodamine B (RB), methyl orange (MO), methyl red (MR), and methyl violet (MV), and isoquinoline antibiotics such as berberine (BER) and palmatine (PAL) with detection limits of 143, 128, 374, 193, 305, 27 and 34 ppb, respectively. Simultaneously, 1 also displayed high adsorption abilities towards these organic molecules. These results indicate that 1 is a favorable material for the simultaneous selective detection and removal of specific dyes and antibiotics from water, being potentially useful in monitoring water quality and treating wastewater. The possible mechanisms of the detection and adsorption are also proposed.

摘要

葫芦脲（CB[6]）基超分子组装体 CB[6]-[NDS]（1，NDS = 2,6-萘二磺酸阴离子）被用于检测染料，如活性蓝 19（RB19）、罗丹明 B（RB）、甲基橙（MO）、甲基红（MR）和甲基紫（MV），以及异喹啉类抗生素，如小檗碱（BER）和巴马汀（PAL），检测限分别为 143、128、374、193、305、27 和 34 ppb。同时，1 对这些有机分子也表现出了很高的吸附能力。这些结果表明，1 是一种从水中同时选择性检测和去除特定染料和抗生素的理想材料，有望用于监测水质和处理废水。还提出了检测和吸附的可能机制。
