for organic luminophores that exhibit highly efficient solid-statefluorescence. It is found that [1]benzogermolo[3,2-b]indole, -benzofuran, and -thiophene-S,S-dioxide emit violet-to-blue light with good-to-high quantum yields in powder form, demonstrating the high potential of such bilaterally unsymmetrical germylene-bridged biaryls as solid-state light-emitting materials (see scheme).
锗桥:在2-苯基苯并杂环上添加Ge桥作为有机发光体的新分子设计原理是有效的,有机发光体表现出高效的固态荧光。发现[1] benzogermolo [3,2- b ]吲哚,-苯并呋喃和-噻吩-S,S-二氧化物以粉状形式发射紫红色到蓝色的光,具有良好到高的量子产率,证明了这种双侧不对称的亚甲基桥接的联芳基作为固态发光材料的潜力很大(请参见方案)。
