- •
Tuning the singlet and triplet state energy level of anthracene derivatives by changing 9,10-substituents to enhance the TTA upconversion.
- •
The C
C linker at 9,10-position significantly reduced the T1 state energy levels, while CC linker does not.- •
Decrease the triplet energy level for energy acceptor can increase the TTET efficiency.
