　　One-dimensional(1D)nanomaterials including wires,tubes,rods,and belts have attracted extensive investigations,due to their unique properties and applications in nanoscale devices.1D micro and nanostructures had been successfully constructed with the help of hydrogen-bonding,π-π stacking,electrostatic,and van der Waals interactions.Herein,We report luminescent 1D organic micro and nanowires and nanofibre from organic metal complex and bio oligopeptide molecule those are aggregated based on metal ·metal interactions,hydrogen-bonding and π-π stacking,respectively.The device fabricated by the nanowires based on metal metal interactions could detect the vapor of volatile organic compounds(VOCs)resulted in changes in the emission properties and observed by naked eyes.On other side,1D fibrous nanostructures were generated with the help of π-π stacking and H-bonding within the oligopeptide.In addition,the strong and extended π-π electronic communication of the anthrancenes along the longitudinal axis of the 1D nanostructure allows significant conductivity along the fibre.
