push–pull (iso)quinolines were studied. The compounds were synthesized by well‐established and straightforward methodologies. The materials exhibited not only emission solvatochromism in a variety of nonpolar solvents, but also tunable halochromism. Some of the compounds remained moderately luminescent after protonation and had a red emissive form, which was used to obtain white‐light emission, both
研究了一系列共轭推挽(异)喹啉的光物理性质。这些化合物是通过完善且直接的方法合成的。该材料不仅在多种非极性溶剂中表现出发射溶剂变色现象,而且还表现出可调节的盐变色现象。一些化合物在质子化后仍保持适度发光,并呈红色发射形式,用于通过控制最初发射蓝绿色光的材料的质子化来获得溶液和薄膜中的白光发射。这种方法在白色有机发光二极管的制造中具有潜在的应用,其中两种形式的单个发射极处于平衡状态。
