鲁米诺被认为是电化学发光（ECL）检测过氧化氢的有效体系。本文设计并合成了具有不同烷基取代基的鲁米诺酰亚胺衍生物。作为一种新型的低分子有机胶凝剂，考察了它们在26种溶剂中的胶凝行为。结果表明，与苯环相连的烷基取代基链的长度和数目对所有化合物在各种有机溶剂中的凝胶化行为起着至关重要的作用。在现有的凝胶剂中，分子骨架中较长的烷基链有利于有机溶剂的凝胶化。扫描电子显微镜和原子力显微镜的观察表明，凝胶因子分子自组装成不同的微/纳米聚集体从点，花，带，棒，和片层褶皱与溶剂的变化。光谱研究表明，存在不同的氢键形成和疏水力，这取决于在分子骨架中的烷基取代基链。本文的工作为新型多功能软材料和具有特殊分子结构的ECL生物传感器的设计和表征提供了理论依据。
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.
