Formula: C15H12O. I found the field of Chemistry very interesting. Saw the article Mechanochromic Delayed Fluorescence Switching in Propeller-Shaped Carbazole-Isophthalonitrile Luminogens with Stimuli-Responsive Intramolecular Charge-Transfer Excited States published in 2020.0, Reprint Addresses Yasuda, T (corresponding author), Kyushu Univ, INAMORI Frontier Res Ctr IFRC, Nishi Ku, 744 Motooka, Fukuoka 8190395, Japan.; Yasuda, T (corresponding author), Kyushu Univ, Grad Sch Engn, Dept Appl Chem, Nishi Ku, 744 Motooka, Fukuoka 8190395, Japan.. The CAS is 94-41-7. Through research, I have a further understanding and discovery of Chalcone.
Herein, the universal design of high-efficiency stimuli-responsive luminous materials endowed with mechanochromic luminescence (MCL) and thermally activated delayed fluorescence (TADF) functions is reported. The origin of the unique stimuli-triggered TADF switching for a series of carbazole-isophthalonitrile-based donor-acceptor (D-A) luminogens is demonstrated based on systematic photophysical and X-ray analysis, coupled with theoretical calculations. It was revealed that a tiny alteration of the intramolecular D-A twisting in the excited-state structures governed by the solid morphologies is responsible for this dynamic TADF switching behavior. This concept is applicable to the fabrication of bicolor emissive organic light-emitting diodes using a single TADF emitter.
