Di-Schiff bases with alkyl spacer (ethyl, butyl and hexyl) showed enhanced light emitting properties in solid state, while quenching was observed for di-Schiff bases with hydrazine spacer. Packing of the molecules via non covalent interactions along with the flexible spacer played the role in dictating the emission properties.

The synthesis and structural characterization of Ni(II) complexes derived from N1,N4-bis(pyridin-2-ylmethylene)butane-1,4-diamine ( L1 ) and N1,N4-bis(1-(pyridin-2-yl)ethylidene)butane-1,4-diamine ( L2 ) is described. The paramagnetic Ni(II) complexes NiL1 and NiL2 were fully characterized and their structures unequivocally determined by single crystal X-ray diffraction techniques. The molecular structures
