Polyphenylenepyridyl Dendrons with Functional Periphery and Focal Points: Syntheses and Applications
For
the first time we report syntheses of a family of functional
polyphenylenepyridyl dendrons with different generations and structures
such as focal groups, periphery, and a combination of phenylene and
pyridyl moieties in the dendron interior using a Diels–Alder
approach and a divergent method. The dendron structure and composition
were confirmed using NMR spectroscopy, MALDI-TOF mass spectrometry,
FTIR, and elemental analysis. As a proof of concept that these dendrons
can be successfully used for the development of nanocomposites, synthesis
of iron oxide nanoparticles was carried out in the presence of thermally
stable dendrons as capping molecules followed by formation of Pd NPs
in the dendron shells. This resulted in magnetically recoverable catalysts
exhibiting exceptional performance in selective hydrogenation of dimethylethynylcarbinol
(DMEC) to dimethylvinylcarbinol (DMVC)
