Four kinds of bis(Ni-salphen) complexes containing a 2-methylenepropane-1,3-diyl linker were synthesised and characterised. Crystal structural analysis revealed that one of the complexes folded into(More)
Colorless, transparent, polymer films including 2-(2'-hydroxyphenyl)imidazo[1,2-a]pyridine (HPIP) derivatives, 1 and 2, are prepared by a spin-coating method. The observed emission spectra upon(More)
Although 2-(2'-hydroxyphenyl)imidazo[1,2-a]pyridine (HPIP) is only weakly fluorescent in solution, two of its crystal polymorphs in which molecules are packed as stacked pairs and in nearly coplanar(More)
