Acridones have found their role in luminescent materials for OLEDs. Most interestingly, showing potential as weak charge transfer thermally activated delayed fluorescence (TADF) emitters, providing narrow photoluminescence. In this work, we present a comprehensive study of donor-acceptor-donor (D-A-D) acridone-amine derivatives TADF and UV electrochromic properties. Structure-property relations...
THE TITLE ACRIDONE ALKALOID [SYSTEMATIC NAME: 1,3,5-trihydr-oxy-2,4-bis-(3-methyl-but-2-en-yl)acridin-9(10H)-one], C(23)H(25)NO(4), has previously been reported as crystallizing in the chiral ortho-rhom-bic space group P2(1)2(1)2(1) [Chantrapromma et al. (2010 ▶). Acta Cryst. E66, o81-o82] but the absolute configuration could not be determined from data collected with Mo radiation. The absolute...
Two new acridone alkaloids, chlorospermines A and B (1 and 2), were isolated from the stem bark of Glycosmis chlorosperma, together with the known atalaphyllidine (3) and acrifoline (4), by means of bioguided isolation using an in vitro enzyme assay against DYRK1A. Acrifoline (4) and to a lesser extent chlorospermine B (2) and atalaphyllidine (3) showed significant inhibiting activity on DYRK1A...
