Solid-state fluorescent behavior of the model benzoxazine monomer, 3,4-dihydro-3,6-dimethyl-1,3,2H-benzoxazine denoted as MM, was firstly reported. Three characteristic fluorescence peaks were observed, i.e., (1) the ultraviolet peak at 317nm with the excitation wavelength of 258nm, (2) the blue emission peak at 450nm with the excitation wavelength of 324nm and (3) the other blue fluorescent peak...
