A new class of highly efficient and stable, blue‐phosphorescent PtII complexes based on a tetradentate chelating framework has been found to exhibit highly sensitive and reversible responses to multiple external stimuli including temperature, pressure, and UV irradiation with distinct phosphorescent color switching—from blue to red or white. Intermolecular excimer formation is the main origin of this
已发现基于四齿螯合框架的新型高效稳定的蓝色磷光Pt II配合物对多种外部刺激(包括温度,压力和紫外线照射)表现出高度敏感和可逆的响应,并具有明显的磷光颜色切换。蓝色到红色或白色。分子间准分子的形成是这种有趣的多反应现象的主要起源。Pt II化合物对单线态氧的高效敏化作用可提高UV光诱导的磷光强度和颜色切换。
