Diels–Alder reaction of anthracene and N-ethylmaleimide on the carbosilane dendrimer

Dendrimers with bicyclo-groups on the periphery were synthesized by the Diels–Alder (DA) reaction between anthracene derivatives, which have 24, 48 and 96 end-groups, and N-ethylmaleimide under the mild condition. The structural information of the DA product on dendritic periphery was obtained from hyperfine structural view of 1H-NMR spectroscopy. The purity of the products was determined by size exclusion chromatography.
