Abstract

The present disclosure provides an organic compound represented by general formula (1-1) or (1-2). <img class="EMIRef" id="458fbda1-b55f-4531-a249-696f1c8a6791-ia01" /> In general formulas (1-1) and (1-2), at least four of bonding sites R<a> to R<h> and at least four of bonding sites R<i> to R<p> are bonded to a skeleton selected from Structure A group. Among the bonding sites R<a> to R<p>, bonding sites not bonded to Structure A group are each independently selected from a hydrogen atom or a substituent. <img class="EMIRef" id="458fbda1-b55f-4531-a249-696f1c8a6791-ia02" /> <img class="EMIRef" id="458fbda1-b55f-4531-a249-696f1c8a6791-ia03" /> In general formulas (2-1) to (2-10), R<1> to R<90> are each independently selected from a hydrogen atom, a deuterium atom, and various substituents. X is an oxygen atom, a sulfur atom, NR<91>, CR<92>R<93>, or SiR<94>R<95>. R<91> to R<95> are each independently selected from a hydrogen atom or a substituent. Bonding positions * represent positions of bonding to the bonding sites R<a> to R<p>.
