Outline of Final Research Achievements

We have developed oxygen bridged V-shaped pi-conjugated materials as promising organic light emitting transistor materials. Two types of DNF-Vs (Ph-DNF-VV and Ph-DNF-VW) were designed and synthesized. Especially, Ph-DNF-VW exhibits high carrier mobility, high thermal stability and high fluorescent quantum yield in solid state. A series of alkyl substituted DNF-Vs were systematically synthesized. Their aggregated structures and luminescence properties were examined. Two types of L-shaped pi-conjugated molecules (DNF-L and DNT-L) were designed and synthesized. These compounds exhibited notable high solubility to common solvents even though no substituent is introduced. Molecular design rules to achieve printable high performance organic light-emitting transistor materials were established.
