竹红菌甲素和乙素是我自新开发的光疗药物。目前还没有人对它们及其类似物的电子光谱作系统地研究。我们详细地研究了它们的吸收和荧光光谱。证明它们在可见光范围内的三个吸收带分别由苝醌共轭体系的ππ跃迁和分子内质子传递引起。它们在稀溶液的荧光光谱由中性单分子荧光峰和它们 Hypocrellin A and B are my newly developed phototherapy drugs. No one has systematically studied the electronic spectra of them and their analogs. We studied their absorption and fluorescence spectra in detail. It is shown that the three absorption bands in the visible range are caused by ππ transition and intramolecular proton transfer of perylenequinone conjugated system. Their fluorescence spectra in dilute solutions consist of neutral single-molecule fluorescence peaks and their
