  • Penta-substituted tetrahydropyrimidines with aggregation-induced emission characteristics and preparation method and use thereof
    Patent number: 8906927
    Abstract: The present invention provides a series of penta-substituted tetrahydropyrimidines with aggregation-induced emission (AIE) characteristics and preparation method and use thereof. The AIE penta-substituted tetrahydropyrimidines have structures shown as formula (I). R1 is selected from a group consisting of linear or branched alkyls and substituted alkyls. R2 and R4 is respectively selected from a group consisting of linear or branched alkyls, substituted alkyls, cycloalkyls, substituted cycloalkyls, aryls, substituted aryls, polycyclic aryls, substituted polycyclic aryls, heterocyclyls, substituted heterocyclyls, aromatic heterocyclyls and substituted aromatic heterocyclyls. R3 is selected from a group consisting of aryls, substituted aryls, polycyclic aryls, substituted polycyclic aryls, aromatic heterocyclyls and substituted aromatic heterocyclyls. The penta-substituted tetrahydropyrimidines can be prepared by multi-component reactions (MCR).
