通过简单的再沉淀法制备了具有不同形貌、相和结构的纳米/微结构的有机光电材料2-氰基-3-（4-（二苯基氨基）苯基）丙烯酸（CDPA）。通过优化制备条件，获得了球形非晶、金刚石和多面微晶的CDPA。在生长溶液中引入聚合物添加剂，可以制备出具有棒状形态的CDPA。在通常的溶液结晶过程中未观察到的CDPA的多晶型物作为1D纳米线（200 - 400 nm（宽度）和3 - 20 μm（长度））获得。粉末X-射线衍射和光学研究证明了纳米线的多晶型结构。扫描电子显微镜和共聚焦荧光显微镜，分别被用来证明不同的形貌制造的纳米/微米结构和发光调谐（从604到519 nm）。
Nano/microstructure fabrication of 2-cyano-3(4-(diphenylamino)phenyl) acrylic acid (CDPA), an organic optoelectronic material, via a simple reprecipitation method produces particles with a different morphology, phase, and structure and a tailored luminescence. Spherical amorphous, diamond, and multifaceted microcrystals of CDPA were obtained by optimizing the fabrication conditions. CDPA with rod-like morphology was produced on the introduction of polymer additives to the growth solution. A polymorph of CDPA, not observed in the usual solution crystallization process, was obtained as 1D nanowires (200−400 nm (width) and 3−20 μm (length)). Powder X-ray diffraction and optical studies demonstrate the polymorphic structure of the nanowires. Scanning electron and confocal fluorescence microscopy, respectively, were used to demonstrate the different morphologies of fabricated nano/microstructures and the luminescence tuning (from 604 to 519 nm).
