S 6 n2 atmosphere for 18 h. after completing reaction, the resulting mixture was poured into water and extracted with ether. the collected organic layer was dried over anhydrous mgso 4 and the solvent was concentrated under reduced pressure. 9,9 dimethyl 9,10 dihydroacridine (dmac) and naphthalene are fused to produce a chromophore 12,12 dimethyl 7,12 dihydrobenzo[a] acridine (dmba).based on dmba, two emitters, 12,12 dimethyl 7 phenyl 7,12 dihydrobenzo[a]acridine (bach) and 3 fluoro 12,12 dimethyl 7 phenyl 7,12 dihydrobenzo[a]acridine (bacf), were designed and synthesized.thanks to the planar structure and weak electron donating. 5d9d69ed4f2797d038b3e6b56ec50e38图片是jenalee的游戏ui 日韩 ,二次元画板中的相关图片之一的详情图，游戏ui 日韩 ,二次元画板共有1350张设计师收藏采集的相关图片素材资源。花瓣网, 设计师寻找灵感的天堂！. In the earlier work, park and co workers [18] reported several small molecules that combined anthracene and 1,3 diphenylbenzene moiety through different numbers of the π conjugated phenylene bridge. the optimal molecule achieved an external quantum efficiency (eqe) of 7.18% with the commission internationale de l’eclairage (cie) coordinates of (0.156, 0.088) in a non doped device.
