Nowadays, fluorescent organic compounds have attracted much research interest due to their academic significance and applications. The present article deals with the fluorescence behaviors of conjugated cyanopyridone based compounds (CP1–5) possessing various donor/acceptor moieties. These compounds showed aggregation-induced emission (AIE) properties in their THF/H₂O mixtures due to the restriction of intramolecular rotation and exhibited a blue emission behavior in their aggregated state. During the AIE study, compound (CP-1) showed a red shift in the emission profile and rest of the compounds exhibited a blue shift in their emission profile. Further, field emission scanning electron microscope (FESEM) and Epi-fluorescence microscopic studies showed that the stronger emission of these compounds is mainly due to the formation of large-sized aggregates in the THF/water mixture than the pure THF.

如今，荧光有机化合物由于其学术意义和应用而吸引了许多研究兴趣。本文讨论了具有各种供体/受体部分的共轭基于氰基吡啶酮的化合物（CP1-5）的荧光行为。这些化合物由于分子内旋转的限制而在THF / H ₂ O混合物中表现出聚集诱导发射（AIE）特性，并且在聚集状态下表现出蓝色发射行为。在AIE研究中，化合物（CP-1）在发射曲线上显示出红移，其余化合物在发射曲线上显示出蓝移。此外，场发射扫描电子显微镜（FESEM）和落射荧光显微镜研究表明，这些化合物的较强发射主要是由于THF /水混合物中形成了比纯THF大的聚集体。
