2,2 ’- (1,4-phenyldivinyl) bis-3,3-dimethylindoline (1), 2,2’- (2), 2,2’- (1,4-phenyldivinyl) bis-benzothiazole (3), 4,4’- (4), 2,2’- (1,4-phenyldivinyl) bis-quinoline (5), 2,2’- Yl) bis-1,3,3-trimethylindoline hydrochloride (6), 2,2 ’- (1,4-phenyldivinyl) bis- Dimethylindoline hydrochloride (7), 2,2 ’- (1,4-phenyldivinyl) bis-8-acetoxyquinoline (8) , 4-phenyldivinyl) bis-8-hydroxyquinoline (9) and the aluminum complex (10) and the zinc complex (11) of 9. The crystal structure of the compound 6 was measured. The maximum luminescence wavelength of compound 1 was 575 nm and the maximum luminescence wavelength of the cationic luminescent compound was red-shifted to 607 nm (6) and 611 nm (7). The maximum emission wavelength of compound 9 was 567 nm, The maximum luminescence wavelength of the material is red-shifted to 605 nm (10) and 610 nm (11). The results show that by changing the molecular structure and changing the electron distribution on the molecule, the luminescence properties are changed, The larger the wavelength, the larger the thermal shift.The thermal analysis shows that the metal complexes 10 and 11 have higher thermal stability than the organic compound molecules, and the electroluminescent material has a wider usable temperature range.
