Synthesis, structure and luminescence of two europium complexes of diphenylimidazophenanthrolines

Abstract

Two new europium coordination compounds, [Eu2(papip)2(PhCOO)6] and [Eu2(phpip)2(PhCOO)6] (papip is 1-phenyl-2-(4-aminophenyl)imidazo[4,5-f][1,10]phenanthroline and phpip 1-phenyl-2-(4-hydroxyphenyl)imidazo[4,5-f][1,10]phenanthroline), have been synthesized hydrothermally and structurally characterized, involving the in situ hydrolysis of phenylacetonitrile to phenylacetate....
