Polydiacetylene-embedded supramolecular electrospun fibres for a colourimetric sensor of organic amine vapour

A colourimetric sensor based on supramolecular fibres composed of polydiacetylene acid and polystyrene-co-poly(4-vinylpyridine) was fabricated through electrospinning. The obtained fibres show high sensitivity and selectivity to organic amine vapour at ppb concentrations.
