A new method for design and assembling of functional materials was presented based on the supra-molecule structure by the co-doping of nanosized metal and organic molecules. With the supra-molecule structure, in which the molecules were adsorbed onto the surface of spherical metal nanoparticles, the excitation of metal nanoparticles on molecules was realized, and the functional extension and enhancement of molecules were achieved. The key issues related to the design were discussed and analyzed. The composite material films with the properties of optical storage in short-wavelength were designed and synthesized experimentally. The results show that, compared with the composite film doped by Methyl orange (MO), the maximum absorption wavelength of MO in composite film with supra-molecular structure was blue-shift about 23nm. The initial decomposition temperature of the composite film was increased by 41℃, and the temperature gap of the decomposition for the composite film was decreased by 51℃. The results indicate the method for design and assembling of functional materials is effective and practical.
