竹红菌甲素(Hypocrellin A,简称HA)是我国首先发现并应用的一种高效光敏剂,并已用来治疗某些顽固性皮肤病.它是从天然资源中分离的一种苝醌颊衍生物(分子式C_(30)H_(26)_O_(10)).作为外源醌,它有可能发展成为一种抗癌药物.关于HA激发态特征已有一些报道.众所周知,激基缔合物的光谱特征是在激发态单体荧光峰的红侧有一个新的,依浓度而变化的无振动结构的宽峰,但由于在极稀HA溶液中,
Hypocrellin A (Hypocrellin A, referred to as HA) was first discovered and applied in our country a highly effective photosensitizer, and has been used to treat some of the stubborn skin disease.It is isolated from natural resources, a perylenequinone cheek Derivatives (molecular formula C_ (30) H_ (26) _O_ (10)). As exogenous quinone, it may develop into an anti-cancer drug.Healthy state on HA has been reported in some reports.It is well known that excitatory association The spectral characteristic of the material is that there is a new broad peak with no vibrational structure according to the concentration on the red side of the fluorescence peak of the excited state monomer. However, due to the extremely weak HA solution,
