UV-Vis and continuous variation plot method were used to study the complexation of γ-cyclodextrin with bromocresol green, and the stoichiometric ratio of the complexation was to be 1∶2. Thermodynamic analysis results show an inverse relationship between temperature and complexation constant, and the change of enthalpy, entropy and free energy of the complexation were -39.988 kJ/mol, 86.400 J/ and -14.245 kJ/mol, respectively, which indicating that hydrophobic effect was the main force to form the complexes.γ-Cyclodextrin and bromocresol green complexes were examined by nuclear magnetic resonance, infrared spectrum and molecular modeling analysis, and was may be the group included in γ-cyclodextrin.
采用紫外-可见分光光度法和等摩尔连续变化法研究了γ-环糊精与溴甲酚绿的包合作用,确定了包合物形成的化学计量比为1∶2;采用热力学方法分析了温度与包合常数之间的关系,计算了包合过程的焓变、熵变及自由能变化分别为-39.988 kJ/mol, 86.400 J/和-14.245 kJ/mol,这表明疏水作用力为主要驱动力;采用核磁共振、分子模拟和红外光谱法对包合物进行了研究,确定了包合物的形成,分析认为这可能是基团进入γ-环糊精腔内导致增色效应。

In this study, we developed the ammonia sensing material by using MCM-41 impregnated with bromocresol green. MCM-41 is one kind of mesoporous molecular sieves. It can be applied to many fields due to well-defined pore shapes, narrow distribution of pore sizes, large pore volumes, high surface area, excellent thermal, hydrothermal, chemical and mechanical stability. And the bromocresol green dye is commonly used as a pH indicator with colorimetric from pH 3.8 to pH 5.4.
本研究之目的是结合变色染剂及中孔洞分子筛MCM-41进行氨气吸附,研究中所选择之变色染剂溴甲酚绿是一种偏酸性之大分子有机染剂,其变色范围在pH 3.8到pH 5.4;而MCM-41由於其孔洞大小分布范围狭窄、孔洞体积大、高比表面积、具有良好的吸附容积、表面反应性强及易於改质等优点,故期望利用此复合材料,经气体吸附达到氨的移除并同时在吸附饱和前能产生显色效果。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
