Abstract

I will present a new iodine functionalized light emitting tris(2,4,6-trichlorophenyl) methyl (TTM) radical, which allows coupling of virtually any organic electron donor as well as acceptor moiety. We present a series of around 30 N-coupled donors and acceptors to TTM and explain why a medium strength donor gives the highest photoluminescence quantum yield. Moreover, I will elucidate the limits for tuning of the emission wavelength within the class of these N-donor coupled TTM emitters. These results will enable new design strategies for more stable and performant light emitting radicals and potentially allow us to expand the range of emission wavelength and overcome the current boundaries beyond the red spectrum.
