General description
Michler′s ketone (MK) is a derivative of benzophenone that shows temperature dependent phosphorescence. It also exhibits triplet-triplet absorption spectra at a lower temperature.
Application
MK can be used as an additive that acts as a photoinitiator in the preparation of dyes. It can also be used as a precursor material in the synthesis of 4,4′-bis{N,N,dimethyl, N (2-ethoxy carbonyl-1-propenyl) ammonium hexafluoro antimonate}benzophenone (MKEA).
