<P><B>Abstract</B></P> <P>New well-defined structurally different 9,10-bis(9-hexyl-6-((E)-styryl)-9H-carbazol-3-yl)anthracene derivatives, shortly named “<B>6a, 6b and 6c</B>”, with side groups having electron donating and withdrawing were systematically synthesized using Suzuki cross-coupling and Vilsmeier-Haack reactions. The impact of electron donating and withdrawing groups and their influence on the molecules photophysical properties has been investigated. The materials showed sky-blue emissions with high internal quantum efficiencies. Based on photophysical investigations the most promising molecule <B>(6a</B>) has been selected and high efficiency OLEDs with external quantum efficiency at very low current efficiency (∼1 mA/cm<SUP>2</SUP>) reaching 5% (doped) were obtained.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Synthesis and characterization of 9,10-bis(9-hexyl-6-((E)-styryl)-9H-carbazol-3-yl)anthracene derivatives </LI> <LI> Thermal, Photophysical and Electrochemical properties of Anthracene derivatives </LI> <LI> Emitters from sky-blue for organic light emitting device applications </LI> <LI> Organic light emitting device fabrication and characterization of 9,10-bis(9-hexyl-6-((E)-styryl)-9H-carbazol-3-yl)anthracene derivatives </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
