CuPc and 8-NTCDI are p-channel and n-channel semiconductors respectively, showing expected and opposing responses to analytes. DMP-NTCDI, on the other hand, because of its ionizable side chain, shows response directions and magnitudes that are not correlated to those of the other two.<\/p>\n<p>The result is a distinct response pattern and unambiguous recognition ability for individual analytes. The differences are even more dramatic if the time evolution of the responses is considered. The three-response patterns obtained from representative polar, nonpolar, acidic, and basic vapors were all different, showing the potential for this approach in rapid, low-cost electronic detection of volatile compounds.<\/p>\n<h6>Related<\/h6>\n<ul>\n<li><a href=\"http:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/adfm.201300245\/abstract\" target=\"_blank\" rel=\"noopener\">Diverse organic field-effect transistor sensor responses from two functionalized naphthalenetetracarboxylic diimides and copper phthalocyanine semiconductors distinguishable over a wide analyte range<\/a> (<em>Advanced Functional Materials<\/em>, Vol. 23, Issue 33, September 6, 2013, pgs. 4094-4104)<\/li>\n<\/ul>\n","protected":false},"template":"","class_list":["post-4727","news","type-news","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.0 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Diverse Organic Field Effect Transistor Sensor Responses - Department of Materials Science &amp;
