Strongly luminescent binuclear aluminium chelate with polymer-like molecular packing and solution-processibility

摘要

A binuclear aluminium(III)chelate with rigid and flexible mixed ligands has been synthesized and structurally characterized,which exhibits polymer-like molecular packing and solution-processiblity,as well as high photoluminescence quantum yield for organic light-emitting diodes(OLEDs);with this new compound as the emissive and host layer,the multi-layer OLEDs prepared via low-cost spin-coating showed encouraging performance.
