A study of Chemically Induced Dynamic Poiarization spectra is made, using a highly time resolved ESR, of photolized anthracenequinone radicals to determine the influence of surfactant micelles on the spin polarization of anthracenequinone anion. It is found that the CIDEP mechanism of photolization is mainly the radical pair mechanism of anthracenesemiquinone radical and of ethylene glycol ketyl R〓〓 or R〓 radical whose center is carbon in anthracenequinone/ethylene glycol system, but there is a certain amount of triplet state mechanism polarization.
分别研究了胶束和微乳液的"笼效应"对蒽醌和苯醌的光解CIDEP的影响,其结果如下:(1)对于蒽醌的CIDEP,在乙二醇溶剂中,极化的蒽醌自由基AQ〓和R〓自由基通过光解经过夺氢反应产生,其CIDEP机理主要是自由基对机理,但也包含了一部分三重态机理。

Results show that intramolecular hydrogen transfer is not favored in view of the energy trend along IHT coordinate in the region such as hypericin's peri region, where two hydrogens of hydroxyl groups bond with a common oxygen of carbonyl group and exists two IHBs in the peri region. However, intramolecular proton transfer often occur in the molecule with hexahydric cycle hydrogen bond, where only one pair of adjacent hydroxyl group and carbonyl group.
此外选择设计了一个具有三个分子内氢键的体系,兼具金丝桃蒽酮和其他苝醌类光敏剂的分子内氢键特点,研究表明两个羟基氢与共同的羰基氧形成的氢键由于存在较高的势垒,很难发生分子内氢传递,即具有金丝桃蒽酮端位结构的分子其分子内氢传递很难发生,而一般的能形成六元环状结构的分子内氢键体系容易发生分子内氢传递。

The metals, such as Fe, Cu and Co, which can be reduced by KBH〓, can not change the catalytic properties obviously if only small amount of them are added to Ni-B alloys; those who can not react with KBH〓, such as Zn〓, are washed out during the preparation, so they also can not change the catalytic properties; while addition of the elements in VIB group, such as Cr, Mo and W, can increase the hydrogenation activity magnificently.
同样,我们通过添加第三组分来修饰Ni-B合金,可以被还原的金属,如Fe、Co、Cu等,少量添加并不能明显改变其反应性能;而与KBH〓不发生反应的金属,如Zn,以离子形式加入后,除了少量离子被吸附在催化剂表面外,基本不残留在催化剂里,因此对反应性能也没有太大的改变;只有VIB族元素,如Cr、Mo、W的加入才会很大改进Ni-B催化剂在蒽醌加氢中的催化性能,尤以Cr的修饰作用最好。
