Four non-ionic europium complexes,〓-phen(11),〓·bipy(12),〓·dia(13) and 〓(14)(TTA=2-thenoyltrifluoroacetone, DBM=dibenzoylmethane, phen=phenanthroline, bipy=2,2'-bipyridine, dia=4,5- diazafluoren-9-one, dmbp=4,4'-dimethyl-2,2,-bipyridine), were synthesised and the triboluminescent phenomena of 12, 13 and 14 were firstly observed. Structure determinations of 11,12 and 14 were carried out. The triboluminescence maxima of 12 and 13 are similar to those of their photoluminescence. X-Ray structure analyses show that Eu atoms all exhibit eight-coordinate tetragonal antiprismatic geometries and complexes 11, 12 and 14 are all centrosymmetric.

二、合成了四个非离子型的铕的配合物：〓、〓、和〓(14)[HTTA=2-噻吩三氟甲酰丙酮，DBM=二苯甲酰基甲烷，phen=邻菲罗啉， bipy=2，2'-联吡啶，dia=4，5-二氮杂芴-9-酮，dmbp=4，4'-二甲基-2，2'-联吡啶]，首次报道了12、13及14的摩擦发光性质，测定了11、12及14的晶体结构，并系统地讨论了晶体结构和摩擦发光活性之间的关系。12及13的摩擦发光光谱的极大值均类似与其相应的光致发光光谱，表明它们有相同的激发态。
