Diamondoid molecules were synthesized from adamantane (C10H 16) using low-temperature plasmas generated in supercritical xenon. The carbon content of the synthesized materials was verified by energy dispersive X-ray spectroscopy, while micro-Raman spectroscopy measurements confirmed that the synthesized materials contained sp3 bonds, the features in the Raman spectra being similar to those found in the Raman spectra of higher order diamondoids. Mass peaks at m/z = 396 were most abundant and might be attributed to C30H36 isomers of hexamantane. The synthesis of this particular type of diamondoid is explained by the fewer necessary cleavages of C-C bonds or C-H occurring to form the diamondoid.
