简单介绍


ossila材料1,5-DTNA  的详细介绍

1,5-DTNA is a ultra-violet light emitter (λem = 350 nm) that is normally used as an acceptor to enable efficient visible-to-ultraviolet (UV) triplet-triplet annihilation upconversion (TTA-UC) with large anti-Stokes shift. It consists of a naphthalene core with two (triisopropylsilyl)ethynyl side arms.

Together with BN-2Cz-tBu, an MR-TADF sensitizer, a green-to-UV TTA-UC system can be realized by using 1,5-DTNA as the emitter acceptor. Photoexcitation of the sensitizer BN-2Cz-tBu and acceptor 1,5-DTNA system with 532 nm laser produces intense UC emission with a remarkable anti-Stokes shift up to 1.05 eV (367 nm ← 532 nm) and upconversion quantum yield up to 7.6% and threshold excitation intensity as low as 9.2 mW cm-2 in solution.

Its isomer 1,4-DTNA (TIPS-NPh) is also available in high purity sublimed and unsublimed grades.
