Aggregation induced emission (AIE) active N-alkyl aminomaleimide dyes with various kinds of N-alkyl groups were synthesized in a one pot process. The synthesized dyes exhibited different emission behaviors depending on the chemical structure of the N-alkyl group, although they had no direct contribution to the π-conjugated system. Chain length, hydroxyl group and branching structure were important in the emission properties such as quantum yield and emission wavelength. Furthermore, it was found that one of the dyes showed mechanochromism; the green emission of crystal samples turned to blue emission after grinding. Single crystal X-ray diffraction analysis revealed that the surrounding around the luminophore was dominant in the emission behaviors.
Novel, Regiospecific Ring-transformation of 1,3- or 1,3,4-substituted Maleimides. Novel Synthesis of 1- and 1,5-substituted Orotamides (2,6-Dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxamides)

N,1- and N,1,5-substituted orotamides were prepared by a new, base-catalysed ring-transformation of 1,3- and 1,3,4-substituted maleimides.A mechanism for the reaction is proposed.

1-Phenyl-3,4-dichloromaleimide, 1-n-propyl-3-bromomaleimide, and 2,3-dichloro-1,4-naphthoquinone have been condensed with various mono- and bis-nucleophiles to yield a range of novel dyes and pigments.Their visible absorption spectra are discussed.
