结论合成的柱撑粘土具有独特的性质，可通过光物理和光化学技术进行表征。适当地选择柱化剂允许对所得到的性质进行剪裁，以增强溶液的吸附特性或修饰有效的微孔。一种独特的化学环境在泥浆粘土中被创造出来。利用气相试剂的光化学猝灭研究可用于监测或表征微孔。我们感谢美国国家科学基金会和迈尔斯实验室对这项工作的支持。
ConclusionSynthetically derived pillared clays possess unique properties which may be characterized through the use of photophysical and photochemical techniques. Proper choice of pillaring agent allows tailoring of the resultant properties of enhance adsorption characteristics from solution or modification of the effective microporosity. A unique chemical environment is created within the pil-lared clays. Photochemical quenching studies utilizing gas-phase reagents can be used to monitor or characterize the microporosity.Acknowledgment. We thank the NSF and Miles Labs for support of this work.
