Chemiresistive Sensor Arrays from Conductive 2D Metal–Organic Frameworks Michael G. Campbell Sophie F. Liu Timothy M. Swager Mircea Dincă 10.1021/jacs.5b09600.s001 https://acs.figshare.com/articles/journal_contribution/Chemiresistive_Sensor_Arrays_from_Conductive_2D_Metal_Organic_Frameworks/2055102 Applications of porous metal–organic frameworks (MOFs) in electronic devices are rare, owing in large part to a lack of MOFs that display electrical conductivity. Here, we describe the use of conductive two-dimensional (2D) MOFs as a new class of materials for chemi­resistive sensing of volatile organic compounds (VOCs). We demonstrate that a family of structurally analogous 2D MOFs can be used to construct a cross-reactive sensor array that allows for clear discrimination between different categories of VOCs. Experimental data show that multiple sensing mechanisms are operative with high degrees of orthogonality, establishing that the 2D MOFs used here are mechanistically unique and offer advantages relative to other known chemiresistor materials. 2015-12-17 10:27:54 Experimental data show Chemiresistive Sensor Arrays offer advantages 2 D MOFs VOC chemiresistor materials
