OLED devices utilizing naphthobenzofurocarbazole emitters exhibited a maximum external quantum efficiency of 7.0%, a remarkably low-efficiency roll-off of 4.8% was achieved at 1000 cd m −2 , and the HLCT mechanism was identified.

This review provides recent advances and insights into photoirradiation reactions of acylsilanes, notably via key nucleophilic siloxycarbene intermediates. Nucleophilic addition, insertion reaction, and cyclization are discussed in terms of reaction mechanism and scope.
