Diels-Alder reaction of anthracene on carbosilane dendrimer

The dendritic macromolecule with 4, 8, 16 and 32 bicyclo end groups on the periphery has been created by the Diels-Alder reaction of anthracene and maleimide. The dendritic skeleton with triple bonds has been prepared by the hydrosilation and the alkynylation of bis(phenylethynyl)dimethylsilane as a core. The peripheral anthracene on dendrimers has been substituted by the reaction of chlorosilyl groups containing dendritic generations and 9-anthracenecarbinol. NMR and MALDI-TOF mass spectrum has characterized these Diels-Alder products. (c) 2005 Elsevier B.V. All rights reserved.
