摘要

采用吸收和圆二色性测量方法研究了光照射对聚赖氨酸(PLL)与甲基橙(MO)手性配合物的影响。在紫外光或可见光照射下,PLL-MO配合物的诱导cd的大小随着偏二聚体染料种类的减少而减小。当更多的光子被照射时,感应cd下降得更快。较低分子量的配合物和较高的温度可使诱导cd降低得更快,在黑暗或再辐照条件下这种变化是不可逆的。

Effect of light irradiation in the chiral complex of poly(l-lysine) with Methyl Orange

The effect of light irradiation in the chiral complex of poly(l-lysine) (PLL) with Methyl Orange (MO) was investigated by means of absorption and circular dichroism (c.d.) measurements. Upon irradiation with ultraviolet or visible light, the magnitudes of the induced c.d. of the PLL-MO complex decreased together with a decrease in skew dimeric dye species. As more photons were irradiated, the induced c.d. decreased much faster. The lowermolecular-weight complex and higher temperature caused faster decrease of the induced c.d. The change was irreversible under dark or re-irradiation conditions.
