- Coumarin 343 introduced LPSQ was successfully synthesized by CuAAC click reaction.
Alkyne substituted Coumarin dye was quantitatively introduced into LPSQ backbone, which gave 25 ~ 100% of Coumarin dye in LPSQ.
LPSQ with 50% of LPSQ showed the highest photoluminescence efficiency, although that with 100% of LPSQ showed the highest absorption, which is probably due to better isolation of relevant amount dye in PSQ backbone. (PL efficiency: 50% > 75% > 25% > 100%)
Obtained LPSQ-C343 will be employed for OLED and laser applications.
