The synthesis of 3-methoxy-benzanthrones was achieved in two steps by Suzuki–Miyaura coupling and BBr3-promoted Friedel–Crafts acylation under mild conditions with an overall yield of 17–74% and tolerance toward various substrates using commercially available reagents.
We report the synthesis of new imino derivatives of acenocoumarol and their chiral separation via HPLC.
Four high-efficiency ultraviolet/deep-blue narrow TADF emitters based on carbazole or carboline donor derivatives and their applications in ultraviolet/deep-blue OLEDs are demonstrated.
The utility of the emission fractions approach is explored in the context of the Stockholm Convention on POPs.
DOBNA's LUMO extension and the introduction of a protecting group in the weak position of the donor group result in high efficiency and long lifetime of the device.
