Organic luminescent materials are indispensable in optoelectronic displays and solid-state luminescence applications. Compared with single-component, multi-component crystalline materials can improve optoelectronic characteristics. This work forms a series of full-spectrum tunable luminescent charge-transfer (CT) cocrystals ranging from 400 to 800 nm through intermolecular collaborative self-assembly
有机发光材料在光电显示和固态发光应用中是不可或缺的。与单组分相比,多组分晶体材料可以改善光电特性。该工作通过分子间协同自组装形成了一系列400至800 nm的全光谱可调谐发光电荷转移(CT)共晶。更有趣的是o -TCP-Cor (x) -Pe (1−x) 、 p -TCP-Cor (x) -Pe (1−x)和o -TCP-AN (x) -TP (1−x)合金是基于共晶通过掺杂策略制备的,相应地实现了从蓝色(CIE [0.22, 0.44])到绿色(CIE [0.16, 0.14])、从绿色(CIE [0.27, 0.56])到橙色(CIE [0.58,0.42]),从黄色(CIE [0.40,0.57])到红色(CIE [0.65,0.35])。该工作为精确合成新型发光有机半导体材料提供了一种有效方法,为开发先进有机固态显示器奠定了坚实的基础。
