Abstract

Much effort has been devoted to rationally manipulating photoluminescence (PL) properties in hybrid metal halides for applications in advanced optical materials. Among them, phase-transition-induced PL change has emerged as a promising approach for efficient PL transformation. However, complicated intermolecular interactions remain challenging, making the underlying mechanisms hard to understand and design. In this work, we present two new organic-inorganic hybrid manganese(II) halides, (C9H13N2)2MnCl4·0.5H2O (1) and (C9H13N2)2MnBr4 (2), which undergo yellow-to-green PL color change with thermally driven phase transitions and recover the initial phase with humid stimulation or recrystallization. Detailed structural analyses revealed that coordination geometry distortion and enhanced intermolecular interactions weaken the crystal field, which results in blue-shifting emission. The diverse structural transformations under multiple stimuli enable applications of 1 and 2 in multilevel information anticounterfeiting. This discovery establishes the interplay between intermolecular interactions and structural deformations in phase-transition-induced PL change, providing valuable insights for the rational design of novel dynamic luminescence materials.

两种杂化卤化锰晶体相变诱导的光致发光变化。

为了使杂化金属卤化物在先进光学材料中的应用，合理地调控其光致发光（PL）性能一直是人们努力的方向。其中，相变诱导的PL变化已成为有效转换PL的一种有前途的方法。然而，复杂的分子间相互作用仍然具有挑战性，使得潜在的机制难以理解和设计。在这项工作中，我们提出了两种新的有机-无机杂化锰（II）卤化物，（C9H13N2）2MnCl4·0.5H2O(1)和（C9H13N2）2MnBr4(2)，它们在热驱动相变过程中发生黄色到绿色的PL颜色变化，并在潮湿刺激或再结晶过程中恢复初始相。详细的结构分析表明，配位几何畸变和增强的分子间相互作用削弱了晶体场，导致蓝移发射。多种刺激下的多种结构转换使1和2在多层次信息防伪中的应用成为可能。这一发现建立了相变诱导的PL变化中分子间相互作用和结构变形之间的相互作用，为合理设计新型动态发光材料提供了有价值的见解。
