Intramolecular Charge Transfer Controls Switching Between Room Temperature Phosphorescence and Thermally Activated Delayed Fluorescence (2018)
Journal Article
Chen, C., Huang, R., Batsanov, A., Pander, P., Hsu, Y.-T., Chi, Z., Dias, F., & Bryce, M. R. (2018). Intramolecular Charge Transfer Controls Switching Between Room Temperature Phosphorescence and Thermally Activated Delayed Fluorescence.

Chemical modification of phenothiazine–benzophenone derivatives is shown to tune the emission behavior from triplet states by selecting the molecular geometry of the intramolecular charge transfer (ICT) state. A fundamental principle of planar ICT (P... Read More about Intramolecular Charge Transfer Controls Switching Between Room Temperature Phosphorescence and Thermally Activated Delayed Fluorescence.

The synthesis of 1-methylphenoxazine via CO2-directed lithiation chemistry is reported. This electron donor was coupled with 2,8-dibenzothiophene-S,S-dioxide with Buchwald–Hartwig chemistry to give a new D–A–D charge-transfer fluorescent molecule 1b....

A series of novel donor–acceptor–donor (D–A–D) compounds featuring dibenzothiophene (DBT) and phenothiazine (PTZ) units are presented. A different degree of steric hindrance between the donor and acceptor fragments is achieved by the systematic chang...
