The first tetra-substituted non-fused chrysene, 3,6,9,12-tetrakis(4-tert-butylphenyl)chrysene7 with blue electroluminescence at 450 nm, and with a radiance of 500 cd m−2, was synthesized by a two-step procedure: direct bromination of chrysene in trimethyl phosphate, followed by palladium-catalyzed cross-coupling of tetrabromochrysene 2 and tert-butylphenylboronic acid 3.
第一种四取代非融合型氯化物——3,6,9,12-四(4-叔丁基苯基)氯化物,具有450 nm的蓝色电致发光和500 cd m−2的辐射强度,是通过两步法合成的:首先在三甲基磷酸酯中对氯化物进行直接溴化,随后进行四溴氯化物和叔丁基苯基硼酸的钯催化交叉耦合反应。
