Noncovalent functionalization of CNTs with small molecules. (a) SWCNTs noncovalently functionalized with pyrenylcyclodextrins, which in a chemitransistor can detect closely related analogues of adamantane and sodium cholate. Reproduced with permission from Ref.87. Copyright 2008, Wiley-VCH Verlag GmbH & Co. (b) Chemiresistive sensor using a composite of SWCNTs functionalized by coordination of a fluorinated tris(pyrazolyl)borate copper (I) complex to the π-sidewalls to provide selectivity to ethylene gas.
