A novel supramolecular chiral hydrogel with enhanced emission was obtained by the co-assembly of achiral thiobarbituric acid-modified gold nanoclusters (TBA-AuNCs) with chiral histidine molecules. Chirality transfer from histidine to the supramolecular hydrogels was achieved through the π–π stacking and intermolecular H-bonding based on molecular recognition. This work gives a creative strategy for the building of chiral nanocluster-based materials.

通过分子识别从金纳米团簇制备手性发光水凝胶

通过非手性硫代巴比妥酸修饰的金纳米团簇 (TBA-AuNCs) 与手性组氨酸分子的共组装，获得了一种具有增强发射的新型超分子手性水凝胶。通过基于分子识别的 π-π 堆积和分子间 H 键，实现了从组氨酸到超分子水凝胶的手性转移。这项工作为构建基于手性纳米团簇的材料提供了一种创造性的策略。
