摘要

Abstract

Three alternating conjugated polymers

namely PFTP

PCzTP

and PSiTP

which combine a thieno[3

]pyrazine (TP) unit with different benzene-based donor units such as 9

9-dioctylfluorene

9-heptadecyl-9

-carbazole and 5

5-dioctyl-5

-dibenzo[

]silole

were synthesized in good yield (

85%) and high molecular weight up to

=5.82×10

via

direct arylation polymerization (DArP). All the resultant polymers exhibit moderate bandgap of about 1.80 eV and strong deep red/near-infrared emitting in the solid state. Among them

the PSiTP-based electroluminescence (EL) devices with an architecture of ITO/PEDOT:PSS/PTAA/emitting layer/TPBi/LiF/Al give the best performance with a maximum luminance of 2543 cd/m

at 478 mA/cm

. This work expands the application scope of high-performance conjugated polymers which can be synthesized by DArP.
