Blue light-emitting oligotriphenylene nanofiber molecular wires exhibit high thermal stability, high fluorescence quantum yield, enhanced conductivity, and stable fluorescence, when compared to the monomer. Fluorescent sensors based on oligotriphenylene nanofibers and their polysulfone composite films enable trace detection, high sensitivity, and high selectivity of nitro-based explosives including nitromethane, nitrobenzene, and 2,4,6-trinitrophenol as well as Fe(III) owing to formation of stable π-electron/charge transfer complexes between the fluorophores and the analytes.
