Abstract: Abstract The speciation of doped-nitrogen (pyridinic N, pyrrolic N, graphitic N and amino N) was controlled by ferric ion catalysis for improving fluorescence of nitrogen-doped carbon dots (NCDs). Comparing to the synthesis of NCDs without… read more here.

Abstract: Imidazolidinone-based α,β-unsaturated iminium ions are the reactive species within countless synthetic protocols in asymmetric organocatalysis. However, (E,Z) and (Z,Z) imidazolidinone iminium ions, i.e. (Z)-CC configurations, have been elusive so far. Herein we describe how in… read more here.
