| Abstract: | Abstract— In order to introduce fullerene cages into an aqueous environment, pendant [60]fullerene-poly(propionylethyle-neimine-co-ethyleneimine) was prepared photochemical-ly. The pendant polymer is highly water soluble, with equivalent aqueous solubilities of the polymer-bound [60]fullerene much higher than the solubility of [60]ful-lerene in toluene. The photochemical reaction between [60]fullerene and secondary amine moieties in the ami-nopolymers likely follows a photoinduced electron transfer-proton transfer mechanism. The pendant polymer structures, which are represented by dehydrogenated di-and tetra-aminofullerene linkages, were characterized by use of proton and 13C NMR, Fourier transform-infrared spectroscopy, gel-permeation chromatography and optical spectroscopic methods. |
