A series of tetraalkylthio substituted tetrathiafulvalenes (TTCn-TTF) was prepared. The syntheses, molecular and crystal structures, and physical properties of TTCn-TTF reveal marked differences from those of BEDT-TTF. The conformational change of TTC1-TTF molecule on the formation of chargetransfercomplexes and the mode of the S…S contacts are described in connection with those of BEDT-TTF compounds

An electro-chemical sensor includes a first electrode, a second electrode spaced apart from the first electrode, and a semiconductor channel in electrical contact with the first and second electrodes. The semiconductor channel includes a trapping material. The trapping material reduces an ability of the semiconductor channel to conduct a current of charge carriers by trapping at least some of the charge carriers to localized regions within the semiconductor channel. The semiconductor channel includes at least a portion configured to be exposed to an analyte to be detected, and the trapping material, when exposed to the analyte, interacts with the analyte so as to at least partially restore the ability of the semiconductor channel to conduct the current of charge carriers.
Provided herein are various bathers and methods of making and using them. In some embodiments, the barriers include a porous crystalline charge-transfer complex and a filler.
