Two series of dehydroabietic acid C-ring derivatives, nitrogen-containing heterocycles (6a-9b) and C-12 substituted compounds (10a-11b), were synthesized and characterized by element analysis, IR, NMR and MS. The UV-vis absorption and fluorescence spectral characteristics of these compounds have been comparatively investigated, and their fluorescence quantum yields were further evaluated. Compared to dehydroabietic acid 1, the absorption and emission spectra of these compounds were bathochromically shifted due to the multiple aromatic rings with rigid planar structures or the larger conjugation of benzene moiety.
合成并表征了两个系列的枞酸 C 环衍生物，包括含氮杂环（6a-9b）和 C-12 取代化合物（10a-11b），通过元素分析、IR、NMR 和 MS 进行了鉴定。比较研究了这些化合物的紫外-可见吸收和荧光光谱特征，并进一步评估了它们的荧光量子产率。与枞酸 1 相比，由于具有刚性平面结构的多个芳环或苯部分的较大共轭，这些化合物的吸收和发射光谱发生了红移。
