WebJul 15, 2024 · RTP crystals with high QE have excellent potential for use in optical probes and high-resolution anti-counterfeiting. It is well known that heavy atoms can increase the spin–orbital coupling (SOC) and thus enhance the ISC rate. Tang's group24presented a novel strategy to enhance the QE by intramolecular triplet–triplet energy transfer (TTET).

WebThe introduction of bromine substituents increased the SOC between singlet and triplet excited states via the heavy atom effect, promoting the ISC process.
