Webbseparated state known as the twisted intramolecular charge transfer (TICT) state.3,6 This state is formed after populating the Franck−Condon locally excited (LE) state2 (see … WebbConsidering that mercury ions (Hg 2+) have long been a threat to human health and the environment due to their persistence, mobility and bioenrichment, the detection and removal of Hg 2+ is of great significance. Therefore, a simple water-soluble naphthalimide derived fluorescent dye with AIEE characteristics was reasonably constructed based on … chase in credit cards
Nat. Chem.：通过抑制卡莎规则来提高发光效率
Twisted 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. Following intramolecular twisting, the TICT state returns to the ground state either through red-shifted … Visa mer Photophysical properties of some fluorescent molecules are well-known to be sensitive to local steric environments. Fluorescence … Visa mer The seminal review by Grabowski, Rotkiewicz and Rettig compiled intuitive, but insightful information and images of TICT formation, and … Visa mer Depending on the proportion of ET and LE character, directly connected D–A systems drastically change their fluorescence emission … Visa mer Because a stronger ET character translates into a more pronounced charge separation, TICT conformations are distinctly induced in polar environments and by substitution of strong donors and acceptors. For … Visa mer Webb6.1.2 Twisted Intramolecular Charge Transfer as a Mechanism for Polarity and Viscosity Sensing 174. 6.1.2.1 TICT- based Viscosity Sensors 176. 6.1.2.2 TICT- based Polarity Sensors 178. 6.1.3 Polarity Sensors Based on Other Mechanisms 178.
