The Problems of Spectrum, Quantum Yield of Phosphorescence, Photosensitization and Photostabilization of Polymeric Acetophenone and Its Derivatives

高分子苯乙酮及其衍生物的光谱、磷光量子产率及光敏化光稳定问题的研究

In this work, the problems of spectrum, quantum yield and lifetime of Phosphoresconce, photosensitization and photostabilization of polymeric acetophenone and its derivatives have been studied.

本工作合成和研究了高分子苯乙酮及其衍生物的光谱、磷光量子产率、磷光寿命以及光敏化、光稳定等问题。

Analogous complexes 3a" and 4a"= CpRu(PPh32, Ar = para-C6H4OMe containing methoxy group at the para-position of gem-diphenyl group were similarly obtained from protonation of the corresponding acetylide complexes via formation of vinylidene intermediate. But only complex 3a'= CpRu(PPh32, Ar2 = fluorenyl is stable in solution, and decomposed to unidentified complex when heated to reflux in THF. Deprotonation of complex 4a in the presence of base gives neutral acetylide complex 6a.

在两个相邻位置的苯基对位位置上接有一甲氧基的衍生物3a"和4a"也可利用类似的质子化反应合成，唯有错合物3a'= CpRu(PPh32， Ar2 = fluorenyl 可以稳定於溶液中，不会进行上述反应，如将其溶於四氢呋喃溶液加热至沸腾则会分解产生无法鉴定的化合物。

The enzyme assays indicated that Pseudomonas sp. ND6 NahG exhibits broad substrate specificities and metabolizes salicylate, acetylsalicylate, sulfosalicylate, 3-methylsalicylate, 5-methylsalicylate and 5 chlorosalicylate.

酶学实验表明，ND6菌株的水杨酸羟化酶具有广泛的底物特异性，它不仅能代谢水杨酸，还能代谢多种水杨酸的衍生物，如乙酰水杨酸、黄基水杨酸、3-甲基水杨酸、5-甲基水杨酸和5-氯水杨酸等。

In this paper, we evaluated the performance of different quantum chemical methods for calculating ^13C chemical shifts of acetylsalicylic acid and its derivatives.

我们用量子化学的方法预测了乙酰水杨酸及其衍生物分子上碳原子的化学位移，并通过比较计算值和实验值得到不同理论计算方法的误差范围。
