donor-π-acceptor-π-donor-type thermally activated delayed fluorescence (TADF) emitter (NyDPAc) using 1,5-naphthyridine as a core moiety. NyDPAc exhibited a high horizontal dipole ratio and thus a high external quantum efficiency (20.9%) even at a relatively low photoluminescence quantum yield (57%). 1,5-naphthyridine as an electron acceptor represents a promising core moiety for efficient TADF materials.
在这项研究中,我们开发了一个供体-π-受体-π-供体型热激活延迟荧光(TADF)发射器(NyDPAc),使用1,5-
萘啶作为核心部分。NyDPAc即使在相对较低的光致发光量子产率(57%)下也表现出较高的
水平偶极比,因此也具有较高的外部量子效率(20.9%)。
1,5-萘啶作为电子受体代表了有效TADF材料的有希望的核心部分。
