为了研究环境因素对有机凝胶的影响，设计并合成了两种脲官能化喹吖啶酮衍生物1a和1b。这两种化合物可以响应于有机测试溶剂中的超声和热刺激，并表现出明显的聚集特性。场效应（FE）-SEM图像的干凝胶显示的三维纤维网络结构的特征凝胶形态。浓度和温度依赖的H-1 NMR谱表明，分子间的π-π和氢键相互作用的凝胶因子的超分子组装过程的主要驱动力。X-射线衍射（XRD），紫外/维斯吸收，和光致发光光谱的研究已经进行，并提供更多的信息来定义凝胶化状态的分子堆积模型。
In investigations into the effects of environmental factors on organogels, two urea-functionalized quinacridone derivatives 1a and 1b 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 of 3D fibrous network structures. The concentration- and temperature-dependent H-1 NMR spectra suggest that the intermolecular pi-pi and hydrogen-bonding interactions of gelators are the main driving forces for the supramolecular assembly process. X-ray diffraction (XRD), UV/Vis absorption, and photoluminescent spectroscopy studies have been carried out and provide more information to define the molecular packing model in gelation states.
