Bis-(8-hydroxyquinoline) mercury nanoribbons with average width of 300 nm, thickness of 50 nm and length of up to tens of micrometers were synthesized by a facile solvothermal method. X-ray powder diffraction and Fourier transform infrared spectrum were employed to determine their structure. The conductivity of a bundle of nanoribbons was also measured, which exhibited linear current-voltage characteristics and excellent photoresponse to light, indicating their potential applications in photoswitch nano-devices in the future.
