The effects of the surfactants, trioctyl phosphine oxide, sodium dodecyl sulfonate and hexadecyl trimethyl ammonium bromide, on the extraction rate of Co^2^+ were investigated. The acceleration in the kinetics in contributed to the associated molecule~2 TOPO taking part in the extraction process directly. The decrement effects of SDS or CTMAB on the rate of extraction kinetics of Co^2^+ with HDEHP were also observed, which caused by the adsorption of molecules of SDS or CTMAB on the interface and decreased the interfacial adsorption amount of HDEHP. In addition, the extraction rate was reduced by a bigger margin in HDEHP-SDS system. This can be explained in terms of the formation of an electric field at the interface.

研究体系中加入不同表面活性剂所引起萃取速率的不同改变：三辛基氧化膦因与HDEHP形成可萃取的Co^2^+活性分子缔合物，降低了萃取过程活化能而使反应加速；十二烷基磺酸钠和十六烷基三甲基溴化铵因占据发生萃取反应的界面区，减小了HDEHP与Co^2^+反应的机会而使反应减速； SDS还因其在界面形成较强的负电场，造成Co^2^+的附加势能而使萃取速率有更大幅度的降低。

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。
