<p>PROBLEM TO BE SOLVED: To provide a novel fused polycyclic compound having a band gap suitable for a red phosphorescence guest material, and T1 energy (lowest excited triplet level energy).SOLUTION: The fused polycyclic compound is expressed by the following general formula [1]: [Formula 1]. In the formula, R1 to R14 is selected from a hydrogen atom, and an alkyl group with 1-4 carbon atoms independently of one another; X1 and X2 represent a hydrogen atom or an aryl group, and only one of X1 and X2 is an aryl group.</p> |
