A phenylenedivinylidenebisquinoline oligomer was obtained by reacting quinaldine with 2,5-bis(octyloxy)terephtalaldehyde via the Knoevenagel reaction by mechanosynthesis. The product was characterized by 1H Homo-J-Resolved NMR, 13C NMR, FT-IR, Fluorescence, UV–Vis spectroscopy and by FAB+ mass spectrometry. X-ray diffraction studies indicate that the molecule is semicrystalline, while laser scanning confocal microscopy shows that the emission comes from the crystals. As a consequence, the morphology and accordingly the PL values in spun films can be changed by varying the spinning conditions. Intrinsic electroluminescent properties are reported using the ITO/M1AMec/Al single layer configuration.
