Amorphous Diamondoid Materials with Extreme Non-Linear Optical Properties

While LEDs dominate today’s lighting market, the search for more efficient, directed white-light sources has begun shifting toward organic molecular materials. Within the DFG-funded FOR 2824 research unit, we are pioneering the use of diamondoid-based organic compounds as sustainable, lightweight materials that convert infrared laser light into directed white-light.

By systematically incorporating functionalized diamondoids such as substituted fluoroaryladamantanes and diamantanes, as well as polymers, including linear diamondoid-based polyamides and polyesters, we can precisely tune their geometric and electronic structures. With the help of DFT studies, we identified that this unique white-light emission (WLE) originates from short-range structural disorder within the material.

These findings pave the way for a new generation of stable, cost-effective photonic materials for large-scale applications. The contributors to this project include Prof. Dr. Peter R. Schreiner (PI), Dr. Saravanan Gowrisankar, and Marius Lang. A selection of our recent findings is detailed in the publications listed here.
