摘要

A carbazole-based fluid plasticizer boosts F8BT film stretchability (fracture strain 18%→44%) and maintains electroluminescence efficiency under strain for flexible electronics.

Abstract

Fully

-conjugated polymers are promising for flexible optoelectronics; however

their inherent brittleness poses a challenge for achieving high-performance flexible electronic devices. In this study

we developed a carbazole-based semiconductor fluid plasticizer

TODPFCZ

to simultaneously enhance the stretchability and optoelectronic properties of poly(9

9-di-n-octylfluorene-

alt

-benzothiadiazole) (F8BT) films using an external plasticizing strategy. The fluid TODPFCZ molecules incorporated into the F8BT matrix disrupted interchain

stacking and crystallinity

which significantly enhanced the stretchability

increasing the fracture strain from 18% to 44% and the crack-onset strain from 5% to 35%. Owing to the efficient energy transfer from TODPFCZ to F8BT

polymer light-emitting diodes (PLEDs) based on the optimized blend films showed stable electroluminescence and maintained efficiency even after being pre-strained up to 15%

revealing outstanding stress tolerance. The blended films also exhibited excellent recoverability and thermoplasticity. This study demonstrates that carbazole-based semiconductor fluid plasticizers provide a versatile and effective pathway for designing high-performance

intrinsically stretchable

fully

-conjugated polymers for durable flexible electronics.
