Abstract
Description
1.化合物1−1の合成
(1)化合物A−2
(1)化合物B−1
陽極(ITO)上に、正孔注入層(HATCN、化学式4、7nm)、正孔輸送層(NPB、化学式5、55nm)、電子遮断層(m−CBP、化学式6、10nm)、発光物質層(35nm)、正孔遮断層(B3PYMPM、化学式7、10nm)、電子輸送層(TPBi、化学式8、20nm)、電子注入層(LiF)、陰極(Al)を順次積層した。
ホストに化学式3の化合物H−1(70重量%)を用いて、ドーパントに化学式9の化合物(30重量%)を用いて発光物質層を形成した。
(2)比較例2
ホストに化学式3の化合物H−1(70重量%)を用いて、ドーパントに化学式10の化合物(30重量%)を用いて発光物質層を形成した。
(3)実験例1
ホストに化学式3の化合物H−1(70重量%)を用いて、ドーパントに化学式2の化合物1−1(30重量%)を用いて発光物質層を形成した。
(4)実験例2
ホストに化学式3の化合物H−1(70重量%)を用いて、ドーパントに化学式2の化合物1−2(30重量%)を用いて発光物質層を形成した。
(5)実験例3
ホストに化学式3の化合物H−1(70重量%)を用いて、ドーパントに化学式2の化合物1−6(30重量%)を用いて発光物質層を形成した。
(6)実験例4
ホストに化学式3の化合物H−1(70重量%)を用いて、ドーパントに化学式2の化合物2−2(30重量%)を用いて発光物質層を形成した。
(7)実験例5
ホストに化学式3の化合物H−1(70重量%)を用いて、ドーパントに化学式2の化合物3−2(30重量%)を用いて発光物質層を形成した。
すなわち、遅延蛍光化合物において、逆系間交差により、遅延蛍光化合物の三重項エネルギーが遅延蛍光化合物の一重項エネルギーに変換され、遅延蛍光化合物の一重項エネルギーが蛍光化合物の一重項エネルギーへ伝達される。このとき、遅延蛍光化合物は、三重項エネルギーと一重項エネルギーとの差が0.3eVより小さい。それにより、遅延蛍光化合物の三重項エネルギーが遅延蛍光化合物の一重項エネルギーへ変換される逆系間交差(Reverse Inter System Crossing;RISC)が起こる。
第1層442は、本発明の遅延蛍光化合物をドーパントとして含み、第2層444と第3層446のそれぞれは、蛍光化合物をドーパントとして含む。第2層444と第3層446の蛍光化合物は、同じであってもよく、異なってもよい。遅延蛍光化合物の一重項エネルギーは、蛍光化合物の一重項エネルギーより大きい。
