A round trip: Readily available dithiocarbamates can undergo ringclosure to give functionalized sulfurheterocycles (see scheme). These heteroaromatic compounds can be further functionalized by directed alumination and subsequently trapped with various electrophiles.
Novel heterocyclic materials are disclosed. The materials contain a fused tetracyclic structure that can improve the properties of OLED devices when the novel heterocyclic materials are incorporated into such devices.
