Abstract

The photophysical properties and electroluminescence (EL) of a series of tris(8-quinolinolate)AlIIIcompounds with substituted aryl moieties in the 5-position were described. The substituent electronic effects, when projected to the quinolinolate chromophore via an aromatic spacer provide an effective tool for remarkable systematic emission-color tuning of both photoluminescence (PL) and EL over a range about 300nm. The devices fabricated using various complexes displayed strong EL. The results show that the substituent electronic effects, when projected to the quinolinolate via an aromatic spacer, provide an effective tool for systematic emission tuning in the complexes.
