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.
