Abstract: Perylene-imide derivatives are industrially important pigments that exhibit a variety of shades from red via maroon to black. In the present investigation, we have synthesised novel perylene-imide derivatives with pyridyl rings in an attempt to apply them for H₂ gas sensors based upon proton acceptors. They are found to remain unbonded in the solid state according to X-ray analysis and are thus available for protonation necessary for H₂ gas sensors. The H₂ gas sensors exhibit a significant change in electrical resistivity by about three orders of magnitude even under 0.01% H₂.
