摘要：
Self-directed Assembly of Photoactive Pery lenediimide-Bridged Silsesquioxane into a Superlong Tubular Structure Introduction of photoactive perylenediimides into the self-directed supramolecular silsesquioxane systems gives superlong tubular structure with length of several hundred micrometers and diameters ranging from 1 to 9 mu m as determined by FE-SEM. XRD demonstrated that the wall of the tubes arranged in lamellar structure. A mechanism has been proposed for the formation of the tubes. The effects of the self-directed and closely packed structure on its optical behaviors are determined by the UV-vis absorption and photoluminescence spectra.
