摘要：

The triboluminescence of three non-ionic europium complexes, Eu(TTA)(3). bipy (1), Eu(TTA)(3). dia (2) and Eu(DBM)(3). dmbp . H2O (3) (TTA=2-thenoyltrifluoroacetonate, DBM=dibenzoylmethanate, bipy=2,2'-bipyridine, dia=4,5-diazafluoren-9-one, dmbp=4,4'-dimethyl-2,2'-bipyridinate), was observed. Structure determinations of 1 and 3 were carried out. The triboluminescence maxima of 1 and 2 are similar to those of their photoluminescence. The disorder of the thienyl ring and CF3 groups in 1 and the disorder of water in the packing of 3 may be responsible for their triboluminescent activity.
