The derivatives of these nanoscale diamondoid materials are already in use in pharmaceutical applications as anti-viral and anti-Parkinsons agents. Nevertheless, in view of potential applications, the use of carbon-based diamondoids is restricted due to their very specific properties. In this respect, the search for other similar nanoscale molecules could open up additional possibilities for novel applications.

Complementary properties

Here, a research group at the University of Stuttgart in Germany study the possibility of forming diamondoids based on boron and nitrogen. The researchers find that boron nitride diamondoids show a high stability and electronic properties that vary with the molecule's size. These complement those of their carbon-based counterparts. This work is based on quantum-mechanical computer simulations.

Electronic applications

Similarly to carbon-based diamondoids, a selective choice of the size of the boron nitride diamondoids leads to specific electronic properties, such as electronic conductance. As opposed to the regular diamondoids, the boron nitride diamondoids shift their electronic bandgap to the semiconducting region. Accordingly, these can be used as nanoscale building blocks in electronics applications complementary to the ones potentially realizable using carbon-based diamondoids.
