Crown ether carboxylic acids constitute main building blocks for the synthesis of terbium containing covalent cross-linked luminescent materials. Both the complexes and the hybrid nanomaterials could exhibit remarkable green emissions in pure water. More importantly, they were found to have a profound effect on the luminescence responses to arginine compared with glutamic acid, histidine, tryptophan, threonine, tyrosine and phenylalanine in aqueous environment. The present study provided the possibility of using a host-guest mechanism as a way of signal transduction based on lanthanide supramolecular hybrid materials.
冠醚羧酸是合成含铽共价交联发光材料的主要结构单元。配合物和杂化纳米材料在纯水中均能发出显著的绿光。更重要的是，与谷氨酸、组氨酸、色氨酸、苏氨酸、酪氨酸和苯丙氨酸相比，它们在水相环境中对精氨酸的发光响应有显著影响。本研究为基于镧系超分子杂化材料的主体-客体机制作为信号转导的一种方式提供了可能。
