Synthesis and NLO behavior of Oligo(phenylenevinylene)-Porphyrin Dendrimers

Dendrons with a porphyrin core and π-conjugated dendron branches with 8 and 16 stilbene groups have been synthesized and characterized. The dendrons used for dendrimer synthesis possessed an all trans configuration. Cubic non-linear optical behavior of the styryl and porphyrin-containing dendrimers was tested via Z-Scan measurements in spin-coated film samples.

► Dendrimers with a porphyrin core and π-conjugated dendron branches have been synthesized.
► Thin films for cubic NLO-characterization via the Z-Scan technique have been constructed.
► The second-generation dendrimer shows a positive NLO-refractive coefficient.
