Ordered crystalline 1D nanomaterial assemblies are prepared from an organic blue-light-emitting material, 1,2,3,4,5-pentaphenyl-1,3-cyclopentadiene (PPCP). The as-prepared PPCP nanostructures exhibit a novel multicolor emission property, that is, blue, green, and red emission can be achieved when irradiating the PPCP nanomaterial assemblies with different wavelengths.
