采用3,4-乙烯二氧噻吩（EDOT）在MIL-101（Ci）的空腔中聚合制备了一系列导电多孔复合材料。通过控制加载到主体框架中的EDOT的量，可以调节复合材料的电导率和孔隙率。这种方法产生的材料具有合理的电子导电性(1.1 X 10(-3) S.cm(-1))，同时保持高孔隙率（S-BET = 803 m(2)/g）。这是一种很有前途的策略，可以获得高度纳米化的导电聚合物，对小气体分子具有很高的可及性，这有利于制造用于检测NO2的化学电阻传感器。
A series of conductive porous composites were obtained by the polymerization of 3,4-ethylenedioxythiophene (EDOT) in the cavities of MIL-101(Ci). By controlling the amount of EDOT loaded into the host framework, it was possible to modulate the conductivity as well as the porosity of the composite. This approach yields materials with a reasonable electronic conductivity (1.1 X 10(-3) S.cm(-1)) while maintaining high porosity (S-BET = 803 m(2)/g). This serves as a promising strategy for obtaining highly nanotextuted conductive polymers with very high accessibility for small gas molecules, which are beneficial to the fabrication of a chemiresistive sensor for the detection of NO2.
