| 英文摘要 | Two novel Eu3+ complexes Eu(CDBM)(3) center dot 2H(2)O and Eu(CCDBM)(3) center dot 2H(2)O have been synthesized (CDBM = 1-( 4-(9-carbazol) phenyl)-3-phenyl-1,3-propanedione, CCDBM = 1-((4-(9carbazol) methyl) phenyl)-3-phenyl-1,3-propanedione). Eu(CDBM) 3 center dot 2H(2)O showed strong internal ligand charge transfer (ILCT) fluorescence and sensitized emission of Eu3+. Due to the charge transfer character, the. uorescence band of CDBM shifted from 403 nm in cyclohexane to 559 nm in acetonitrile. Photophysical studies demonstrated that no energy was migrated from the ILCT excited state of the ligands to Eu3+, and that Eu3+ was sensitized by the triplet state which was localized in the 1,3-diphenyl-1,3-propanedione (DBM) part. The quantum e. ciencies of Eu3+ in the three complexes are in the order Eu(DBM)(3) center dot 2H(2)O > Eu(CCDBM)(3) center dot 2H(2)O > Eu(CDBM)(3) center dot 2H(2)O in both solution and the solid state. The energy transfer pathways in the three Eu3+ complexes were discussed in detail. Based on the systematic photophysical studies, a new guideline for the organo-lanthanide light emitting materials has been proposed: ILCT should be avoided during molecular modi. cation. |
