A series of novel fluorescent compounds was isolated from condensation mixtures of citric acid and specific β-amines. Their chemical structure was determined using 1H, 13C and HSQC experiments, elemental analysis data, high resolution and fragmentation spectra ESI-MS analyses. These compounds consisted of five-membered ring fused 2-pyridones. The fluorophores exhibited quantum yields as high as 79%
从柠檬酸和特定的β-胺的缩合混合物中分离出一系列新型荧光化合物。使用1 H,13 C和HSQC实验,元素分析数据,高分辨率和碎片光谱ESI-MS分析确定了它们的化学结构。这些化合物由五元环稠合的2-吡啶酮组成。荧光团的量子产率高达79%。
