This synthesis improves photoluminescence in poly(n-vinylcarbazole) using anthracene, indicating valuable design strategies for OLEDs.

Photoluminescence quantum yield increased significantly from 0.5% to 28.9% with a PMMA/PVK–An blend.
Structural analyses confirmed the successful integration of anthracene moieties into the polymer backbone at a 3:1 ratio.
Time-resolved photoluminescence showed reduced excimer formation in PVK–An, suggesting improved emission efficiency.
The findings highlight the importance of side-chain engineering in developing advanced blue-emitting polymers for OLED applications.

Santos et al. (2025) studied this question.
