This paper reports the synthesis, characterisation and photophysical investigation of the homologous series of blue-emitting pentacoordinated AlQ′2L complexes 1-6, where Q′ is 2-methylquinolin-8- olate and L is a phenolate substituted in para to the oxygen donor atom. Both electron attracting and electron releasing substituents have been considered. Also binuclear complexes of formula Q′2Al-L′- AlQ′2, where L′ = OC6H4C 6H4O, OC6H4(CH2) 3C6H4O and OC6H4C(CH 3)2C6H4C(CH3) 2C6H4O have been synthesised and characterised. These are interesting blue-emitting materials for OLED (organic light emitting diode) fabrication. A comparison between computational and experimental results allowed the description of the absorption and fluorescence processes. A study of the frontier orbitals involved in the electric conduction and fluorescence emission has been performed. Influences of the phenolate-based ligands on the compounds spectroscopy have been particularly taken into account. The Royal Society of Chemistry 2006.
