Webb27 apr. 2024 · In the excited state of regular rhodamines (e.g., rhodamine B (RhB)) the dialkylamine groups form the twisted-internal-charge-transfer (TICT) state through a C-N bond rotation, which leads to ... Webb31 mars 2024 · Azines are interesting compounds exhibiting aggregation-induced-emission (AIE) and twisted-intramolecular-charge-transfer (TICT) properties that have exciting prospects in chemosensing and bioimaging applications. They commonly have symmetrical structures and there is no report on red-emissive unsymmetrical azines.

WebbTwisted intramolecular charge transfer (TICT) is an electron transfer process that occurs upon photoexcitation in molecules that usually consist of a donor and acceptor part linked by a single bond. Webb15 sep. 2010 · Molecular rotors are a group of fluorescent molecules that form twisted intramolecular charge transfer (TICT) states upon photoexcitation. When intramolecular twisting occurs, the molecular rotor returns to the ground state either by emission of a red-shifted emission band or by nonradiative relaxation. The emission properties are … brazuca play baixar
