Smart textiles exhibiting optical response to external temperature stimuli are promising functional materials for a wide range of applications. It is critical yet challenging to endow these materials with high‐contrast, vivid, and real‐time optical signals, such as changes in color or fluorescent emission, for the indication of heating and/or cooling. A thermoresponsive dye system featuring simultaneous thermochromism and thermofluorescence is developed and applied to dyeing of polyester fabrics. The dye system is constructed by encapsulating a solution of indenoquinacridone (IQA) in aliphatic alcohol into SiO2 nanoparticles. The dual‐output response relies on the mechanism of solvent‐modulated dissociation/aggregation of the IQA molecules. Upon heating, the dye system and the dyed fabric exhibit clear color change and high‐contrast, turned‐on fluorescence, in a real time and highly reversible manner. The thermoresponsive temperature can be tailored by varying the aliphatic alcohol solvent with different melting point. The integration of high‐contrast dual optical outputs into this programmable, robust, and reversible dye system lays the foundation for its employment in a wide range of challenging applications in smart textiles.

高性能热响应双输出染料系统，适用于智能纺织品
对外部温度刺激表现出光学响应的智能纺织品是有希望的功能材料，可广泛应用于各种应用中。使这些材料具有高对比度，生动，实时的光学信号（例如颜色或荧光发射的变化），以指示加热和/或冷却，这是至关重要的，但也具有挑战性。开发了同时具有热致变色和热荧光特性的热敏染料体系，并将其应用于涤纶织物的染色。通过将茚并喹ac啶酮（IQA）在脂肪醇中的溶液封装到SiO 2中来构造染料系统。纳米粒子。双输出响应取决于IQA分子的溶剂调节解离/聚集机制。加热后，染料系统和染色的织物可以实时，高度可逆地显示出清晰的颜色变化和高对比度，开启的荧光。可以通过改变具有不同熔点的脂族醇溶剂来调节热响应温度。将高对比度的双光学输出集成到此可编程，耐用且可逆的染料系统中，为在智能纺织品中广泛使用具有挑战性的应用奠定了基础。
