Abstract: 

A novel approach for the bottom‐up construction of hybrid
organic–inorganic nanocomposites with an intimate arrangement between sp³‐carbon
3D molecular‐size nanodiamonds (diamondoids) and a coated palladium
surface as nanolayer is reported. The construction process is conducted
stepwisely from the gas phase, using first controlled vapor‐phase
self‐assembly of tailor‐made functionalized diamantane derivatives,
followed by low‐temperature (45 °C) chemical vapor deposition of an
organometallic complex in a reducing H₂ atmosphere over the
self‐assembled diamondoid scaffold. The use of self‐assemblies of
primary diamantane phosphine and phosphine oxide, which are produced
with high structural uniformity and reproducibility, yields new hybrid
diamondoid‐palladium materials incorporating PdOPHdiamantane bonding
motifs. Additional investigations provide evidence for a very
challenging issue in the intimate construction of sp³‐C/metal
scaffolds. Scanning electron microscopy and transmission electron
microscopy microscopies combined with X‐ray photoelectron spectroscopy
surface analysis and EDX bulk analysis confirm the formation of
diamondoid‐palladium organohybrids with unique surface layering. The
vapor phase‐controlled mild synthetic process allows excellent control
over nanocomposite formation and morphology from molecular‐level
modifications. As such, this bottom‐up composite building process
bridges scales from the molecular (functionalized diamondoids) over
nanoscopic (self‐assemblies) to microscopic regime (hybrids), in the
challenging association of transition metals with an electronically
saturated sp³‐carbon organic host material.
