Indolesynthesis by a gold(I)‐catalyzed intermolecular formal [4+2] reactionbetween 1,3‐diynes and pyrroles has been developed. This reaction involves the hydroarylation of 1,3‐diynes with pyrroles followed by an intramolecular hydroarylation to give the 4,7‐disubstituted indoles. This reaction can also be applied to the synthesis of carbazoles when indoles are used as the nucleophiles instead of
Provided is a thermally activated delayed fluorescent emission-type organic electroluminescent device (organic EL device) having a low driving voltage, high luminous efficiency, and a long lifetime. The organic EL device is a delayed fluorescent emission-type organic EL device including one or more light-emitting layers between an anode and a cathode opposite to each other, wherein at least one of the light-emitting layers contains a para-biphenylcarbazole compound-type host material represented by the general formula (1), and an indolocarbazole compound-type thermally activated delayed fluorescent light-emitting material including an indolocarbazole ring in a molecule thereof.
