Abstract
A chemiresistive vapor sensor compound for detecting target vapors can comprise a perylene-tetracarboxylic diimide (PTCDI) core according to structure (I): where R can be a morphology control group or -A'-D′, A and A′ can be independently a linking group, D and D′ can be independently a strong electron donor which transfers electrons to the PTCDI core sufficient to form an anionic PTCDI radical of the PTCDI core, and R1 to R8 can be independently a side group. A chemiresistive vapor sensor for detection of a target compound can comprise an assembly of nanofibers formed of the chemiresistive sensor compound and a pair of electrodes operatively oriented about the assembly of nanofibers to allow electrical current to pass from a first electrode in the pair of electrodes through the assembly of nanofibers and to a second electrode in the pair of electrodes.
