In investigations into the effects of environmental factors on organogels, two urea‐functionalized quinacridone derivatives 1 a and 1 b have been designed and synthesized. These two compounds can respond to ultrasound and thermal stimuli in the organic test solvents, and exhibit pronounced aggregation properties. The field‐effect (FE)‐SEM images of xerogels show the characteristic gelation morphologies
在研究环境因素对有机凝胶的影响时,已设计并合成了两种脲官能化的喹ac啶酮衍生物1a和1b。这两种化合物可对有机测试溶剂中的超声和热刺激作出反应,并表现出明显的聚集特性。干凝胶的场效应(FE)-SEM图像显示了3D纤维网络结构的特征性凝胶形态。浓度和温度依赖性11 H NMR光谱表明胶凝剂的分子间π-π和氢键相互作用是超分子组装过程的主要驱动力。X射线衍射(XRD),UV / Vis吸收和光致发光光谱学研究已经开展,并提供了更多信息来定义胶凝状态下的分子堆积模型。
