In the present study, two fluoran molecules (TH1 and TH2) have been synthesized, and their reversible thermochromic properties have been investigated. This work demonstrates the thermochromic reversibility of the fluoran. Furthermore, the three-component mixtures that comprising fluorans (TH1/TH2), bisphenol-A (color developer), and methyl stearate a low melting solvent were used to examine the thermochromic behavior with sturdy heating and cooling rates and the thermochromic properties of the fluorans were detailed using UV-Vis, reflectance and FT-IR spectroscopic techniques. Finally, test strip similar to pH paper and acrylic fiber a versatile material used as thermal indicators also been successfully made from these two fluoran derivatives.
在本研究中，合成了两种荧烷分子（TH1和TH2），并研究了它们的可逆热致变色性能。这项工作证明了荧烷的热致变色可逆性。此外，使用包含荧烷（TH1/TH2）、双酚A（显色剂）和硬脂酸甲酯（一种低熔点溶剂）的三组分混合物，以稳定的加热和冷却速率来研究热致变色行为，并使用紫外可见光谱、反射光谱和傅里叶变换红外光谱技术详细研究了荧烷的热致变色性能。最后，还成功地由这两种荧烷衍生物制成了类似于pH试纸的测试条以及用作热指示剂的通用材料腈纶。
