Materials exhibiting multi-stimuli responsive luminescence are useful for applications in information encryption, fluorescence sensors, and optoelectronic devices. Herein, we report the development of fluorenyl-difluoroboron-β-diketonates that provide multi-stimuli responsive fluorescence. These complexes exhibit weak fluorescence in a diluted solution and aggregation-induced emission in the solid-state. The solid-state emission colour of these complexes can be tuned by grinding-fuming and grinding-heating cycles. Our experimental data reveal that propeller-shaped donor-acceptor structure and loose molecular packing structure induced by long alkyl chains are the key factors related to the stimuli response sensitivity. Furthermore, we demonstrate the information-process applications of these materials for use in a thermochromic logic gate device.

表现出多刺激响应发光的材料可用于信息加密，荧光传感器和光电设备中。在这里，我们报告了芴基-二氟硼-β的发展-二酮酸酯提供多刺激响应性荧光。这些复合物在稀释的溶液中显示出微弱的荧光，并在固态下表现出聚集诱导的发射。这些配合物的固态发射色可通过磨烟-发烟和磨光-加热循环进行调节。我们的实验数据表明，由长烷基链诱导的螺旋形供体-受体结构和松散的分子堆积结构是与刺激反应敏感性相关的关键因素。此外，我们演示了这些材料在热致变色逻辑门器件中的信息处理应用。
