具有持久的室温磷光(p-RTP)或有效的磷光机械变色特性的发光体在光电子材料领域具有重要的潜在应用。到目前为止，在一些不同分子结构的发光分子中已经观察到了p-RTP和显著的磷光机械变色现象。然而，从单个发光体中分别实现不同晶型的p-RTP和高对比度磷光机械致变色仍然是一个有价值和挑战性的课题。在本工作中，报道了一种新的金(I)配合物的两个多晶型1B和1YG，分别具有蓝色和黄绿色发光。有趣的是，1B表现出高对比度的磷光机械变色行为，而1YG表现出持久的室温磷光效应。这是从单个发光体同时获得具有高对比度磷光机械变色或持久室温磷光特征的双重用途晶体材料的第一个例子。
Luminophores with persistent room-temperature phosphorescence (p-RTP) or effective phosphorescent mechanochromism features have significant potential applications in the field of optoelectronic materials. Until now, p-RTP and remarkable phosphorescent mechanochromism phenomena have been observed in some luminescent molecules with different molecular structures. However, separately realizing p-RTP and high-contrast phosphorescent mechanochromism in different polymorphs from a single luminophore is still a valuable and challenging topic. In this work, two polymorphs 1B and 1YG of a new gold(I) complex with blue and yellow-green luminescence, respectively, are reported. Interestingly, 1B exhibits high-contrast phosphorescent mechanochromic behavior, while 1YG exhibits a persistent room-temperature phosphorescence effect. This is the first example of simultaneously obtaining double-purpose crystalline materials with a high-contrast phosphorescent mechanochromism or persistent room-temperature phosphorescence feature from a single luminophore.
