M. Lehmann et al., Dendrimers consisting of stilbene or distyrylbenzene building blocks synthesis and stability, TETRAHEDRON, 55(47), 1999, pp. 13377-13394
On the basis of Wittig-Homer reactions and protection group techniques comp
ound 7 for the core and the components 9a-c and 11a-c for the dendrons were
prepared and linked in the final step. The convergent synthesis yielded co
nstitutionally and configurationally pure dendrimers (2a-c, 2a'-c') which c
onsist of distyrylbenzene units. Their thermo-oxidative stability in the pr
esence of air was studied by chemiluminescence and compared to the dendrime
