A colorful bunch: Dyes based on 2,2′‐biindenyl fluorophores exhibit tunable solid‐state emission colors that cover the whole visible region from blue to red. The nonplanar conformation of the dyes in crystals result in bright deep‐blue emission for 1–3, and green emission for 4. Furthermore, the two crystalline forms of BDY‐IN (BDY‐O and BDY‐R) exhibit different optical properties.
一束五颜六色的染料:基于2,2'-联茚基荧光团的染料显示出可调的固态发射色,覆盖了从蓝色到红色的整个可见区域。在晶体中的染料的非平面构象导致明亮的深蓝色发光1 - 3,以及用于绿色发射4。此外,BDY-IN的两种结晶形式(BDY-O和BDY-R)表现出不同的光学性质。
