Abstract: An exotic ternary S, N, O heterocumulene OSNSO in syn-syn (A) and syn-anti (B) conformations has been generated in the gas phase through flash vacuum pyrolysis of CF3S(O)NSO at 700 K. Upon visible light irradiation… read more here.

Abstract: The solid-state fluorescence of fluorophores is usually weakened or quenched by strong π-π interactions. Here, the solid-state fluorescence quantum yields (ΦSF) of tetrasubstituted tetrahydro-pyrimidines (TTHPs) are enhanced rather than decreased/or... read more here.
