A FACILE SYNTHESIS OF 2,5-DISUBSTITUTED INDOLE DERIVATIVES AS NEW FLUORESCENT DYES

[摘要]：A novel bis-arylated indole derivative, 2,5-bis(2-naphthyl)-1-methyl)-1H-indole, was prepared and characterized. This compound shows the highly pure blue emissions both in solution and solid state which were ascribed to the expanded pi-conjugation by introduction of two 2-naphthyl groups at the 2 and 5 positions on the indole ring. From X-ray crystallographic results this molecule exhibited the intermolecular CH-pi it interactions which consisted two dimensional (2D) herringbone structure.
