Influence of degree of methyl methacrylate polymerization on spectroscopic properties of ethyl 5-(4-aminophenyl)- and 5-(4-dimethylaminophenyl)-3-amino-2,4-dicyanobenzoate

► The fluorescence excitation and emission spectra in MM possess a complex nature. ► Fluorescence decay kinetics for different degrees of polymerization of MM were investigated. ► The ICT fluorescence FWHM for EDMAADCy shows a linear dependence on the time of polymerization. ► EDMAADCy can be used as fluorescence probe for monitoring the polymerization process of MM
