In article number 1800116, Sergei A. Ponomarenko, Maxim S. Pshenichnikov, Dmitry Yu. Paraschuk, and co-workers propose an innovative concept of molecular self‐doping. The art shows how a highly luminescent dopant emerges as a minute‐amount by-product during the host material synthesis to enhance luminescence of organic crystals. The self-doping concept opens an easy route to highly luminescent semiconductor organic crystals for optoelectronics applications

Modern light-emitting devices such as top-level TV screens are based on organic luminescent semiconductor materials. The two key requirements for them are efficient luminescence and high charge carrier mobility. The latter requires tight molecular packing readily achieved in organic semiconductor single crystals, but it also results in inhibiting the light emission because of luminescence quenching. This dichotomy is resolved by doping of the host crystals with highly luminescent organic molecules which requires their chemical synthesis and subsequent smooth embedding into the host.

Natural photosynthetic complexes have evolved to successfully operate under extreme low light conditions. Their tubular structure inspired the scientists to mimic nature with artificial nanotubes made of smart molecules, which are “programmed” to self-assemble in tubes without any human intervention. Changing the nanotubes sizes, which is of great interest for potential applications, requires re-programming the molecules.
