光敏的

The pigments synthesized from 2, 7-diaminoflurenone consistently show better photosensitivity than that containing anthraquinone. A plot of the E1/2 values against the Hammett constant σ was obtained for the pigments which have different substituents in the anilide ring. The plot reveals that neither a strong electron-releasing group, such as methoxy, nor a electron-withdrawing group, such as nitro-group, enhances the sensitivity of the photoreceptor in which these pigments are used as CGL materiel.

芴酮类偶氮染料的光敏性优于蒽醌类偶氮染料，其偶合基酰胺芳环取代基为强的给电子基团或强的吸电子基团时都不利于其光敏性的提高，只有当取代基基团为氯时其表现出最好的光敏性，这一结果与Law等人的研究结果相同。

At present, the application in the packaging business card printing and membership card making the UV light oil formation, in addition polymerization, the film uses initiator aggregation and energy initiating two forms (both called conglutinate, that is, light oil system of conglutinate in the ultraviolet radiation occurs under resin polymorization formation of varnish film, known as UV-curing on).

目前，应用在包装制卡和会员卡制作制品上的UV光油，除氧化聚合形成外，薄膜采用引发剂引发聚合和能量引发聚合两种形式（均称为光敏树脂，即光油体系的光敏树脂在紫外线照射下树脂发生聚合反应形成的光油薄膜，称为紫外线固化上光油）。

The maximum absorption peak was at long wavelength (＞650nm), extinction coefficient achieves 10〓 degree, which was one degree higher than HpD. The study has revealed that CPD photosensitizer appeared blue movement under the relevant body environment. The spectra parameters provided basis for selecting light source of PDT. Measurement system which measured singlet oxygen and its quantum yields within the infare range had been set up and the quantum yields of singlet oxygen for CPD were reported: the quantum yields of singlet oxygen for CPD〓 was the highest (φ=0.83) while he quantum yields of singlet oxygen for CPD〓 was the lowest (φ=0.83). Photobleaching's half life time was studied.

Among the arylazides, fluorinated aryl azides are exceptionally promising because upon photoactivation, they lead to much more efficient photolabeling than non-fluorinated arylazides.

目前，尽管已经有一些磷脂光敏探针用于膜蛋白研究的报道，但是还没有使用以上两种芳基叠氮基团作为光敏基团的报道，在磷脂的极性头基上引入光敏基团的报道也极少见。

Compared with HA in water-contained organic solvents, the pigment in micelle had higher pKa value and higher fluorescence quantum yield. Moreover, the quantum yield of active species produced from photosensitization, 1O2 and ·OH, increased as well. As a result, the photosensitivity of HA was enhanced.

相对于含水有机体系，HA在胶束中基态的 pKa值升高，荧光量子产率增大，光敏反应产生的活性中间体1O2 和·OH的产额增加，从而提高了其光敏活性，这在光敏损伤作用中具有重要的生物学意义。

Because vegetation sourced photosensitizers are unstable, low concentration in plant and insignificant effect, we put our emphasis on a kind of chemical photosensitizers - xanthene.
