Luminol is considered as an efficient sycpstem in electrochemiluminescence (ECL) measurements for the detection of hydrogen peroxide. In this paper, new luminol imide derivatives with different alkyl substituent chains were designed and synthesized. Their gelation behaviors in 26 solvents were tested as novel low molecular mass organic gelators. It was shown that the length and number of alkyl substituent chains linked to a benzene ring in gelators played a crucial role in the gelation behavior of all compounds in various organic solvents. Longer alkyl chains in molecular skeletons in present gelators are favorable for the gelation of organic solvents. Scanning electron microscope and atomic force microscope observations revealed that the gelator molecules self-assemble into different micro/nanoscale aggregates from a dot, flower, belt, rod, and lamella to wrinkle with change of solvents. Spectral studies indicated that there existed different H-bond formations and hydrophobic forces, depending on the alkyl substituent chains in molecular skeletons. The present work may give some insight to the design and characteristic of new versatile soft materials and potential ECL biosensors with special molecular structures.
鲁米诺被认为是用于检测过氧化氢的电化学发光 (ECL) 测量中的有效体系。在本文中，设计并合成了具有不同烷基取代链的新型鲁米诺酰亚胺衍生物。测试了它们在 26 种溶剂中的胶凝行为，作为新型低分子量有机凝胶剂。结果表明，凝胶剂中连接到苯环上的烷基取代链的长度和数量对所有化合物在各种有机溶剂中的胶凝行为起着至关重要的作用。分子骨架中较长的烷基链有利于有机溶剂的胶凝。扫描电子显微镜和原子力显微镜观察表明，凝胶剂分子自组装成不同的微/纳米级聚集体，从点、花、带、棒和薄片到皱折，随溶剂的变化而变化。光谱研究表明，根据分子骨架中的烷基取代链，存在不同的氢键形成和疏水相互作用力。本工作可能为设计和特性提供一些见解具有特殊分子结构的新型多功能软材料和潜在的 ECL 生物传感器。
