High‐Pressure Synthesis of Boron‐Doped Ultrasmall Diamonds from an Organic Compound

The first application of the high-pressure–high-temperature (HPHT) technique for direct production of doped ultrasmall diamonds starting from a one-component organic precursor is reported. Heavily boron-doped diamond nanoparticles with a size below 10 nm are produced by HPHT treatment of 9-borabicyclo [3,3,1]nonane dimer molecules.
