A compound of formula (I) or (III) (Formulae (I), (III)) wherein: one Y is a substituent R1 bound directly to the fluorene unit of formula (I) by an sp3-hybridised carbon atom; the other Y is an aryl or heteroaryl group Ar1 that may be unsubstituted or substituted with one or more substituents; Ar2 is an arylene or heteroarylene group; R2 is a substituent; b is 0, 1, 2, 3 or 4; c is 0, 1, 2 or 3; and X is a group of formula (II): (Formula (II)) wherein Z is O or S; R3 independently in each occurrence is a substituent; each x is independently 0, 1, 2 or 3; and * is a bond to the fluorene unit of formula (I).The compounds may be used as host materials for phosphorescent dopants in organic light-emitting devices.

Benzopyranones were successfully synthesized using Cu(I)-mediated C-O bond formation in subcritical water. A number of benzopyranone derivatives including polymethoxy benzopyranones, benzopyranopyridones, chromenoindolones, and furochromenones were synthesized in satisfactory yield. This methodology was further applied to synthesize the intestinal microbial metabolites, urolithins A, B, and C, which were found to exhibit potent antioxidant activity.
