新设计的具有羽毛状结构的荧光团系统通过经由溴化、醚化和脱甲硅烷基化的简洁反应序列连接双蒽构建单元来构建。光谱表征表明，所有的荧光团系统实现了高的光吸收率和高的发射效率，通过防止紧密间隔的蒽发色团相互作用，以减少伴随的能量损失的荧光猝灭。荧光团系统用于制备捕光二分体材料的应用已经成功地证明了它们作为多功能光功能工具的潜在效用。
Newly designed fluorophore systems with feather‐like structures were constructed by connecting bisanthracene building units via a concise reaction sequence of bromination, etherification, and desilylation. Spectroscopic characterizations revealed that all of the fluorophore systems achieved high light absorptivity and high emission efficiency by preventing closely spaced anthracene chromophores from mutual interactions to reduce concomitant energy loss by fluorescence quenching. The application of fluorophore systems for the preparation of light‐harvesting dyad materials has successfully demonstrated their potential utility as versatile photofunctional tools.
