    • A thermal indicator material and method of producing a material capable of a thermochromic transition upon undergoing a temperature change. The material comprises a plurality of compounds having the following structure: (I) wherein R 1 -R 6 = a hydrogen, substituted or unsubstituted alkyl radical, substituted or unsubstituted alkoxy radical, substituted or unsubstituted aryl radical, substituted or unsubstituted thioalkyl radical, substituted or unsubstituted trialkylsilyl radical, substituted or unsubstituted acyl radical, substituted or unsubstituted ester radical, substituted or unsubstituted amine radical, substituted or unsubstituted amide radical, substituted or unsubstituted heteroaryl or substituted or unsubstituted aryl radical n is between 1 and 1000, m is between 0 and 1000, and 1 is between 1 and 1000; with added small molecules, the small molecule additive having the following structure: R-Ar-R' , R-X, linaer alkane, or oligoethylene oxide small molecules with molecular weight less than 1,000 AMU wherein R-R' = a hydrogen, substituted or unsubstituted alkyl radical, substituted or unsubstituted alkoxy radical, substituted or unsubstituted thioalkyl radical, substituted or unsubstituted trialkylsilyl radical, substituted or unsubstituted acyl radical, substituted or unsubstituted ester radical, substituted or unsubstituted amine radical, substituted or unsubstituted amide radical, substituted or unsubstituted heteroaryl or substituted or unsubstituted aryl radical and Ar = a substituted or unsubstituted aromatic or heteroaromatic radical including but not limited to benzene, thiophene, naphthalene, flourene, anthracene, pyridine, indine, biphenyl, phenanthrene, and furan X = a halogen (F, Cl, Br, or I). The thermochromic transition of the material is reversible. The thermochromic transition is a two step transition, such that when the samples are heated above the thermochromic transition temperature followed by a rapid cooling to a temperature below the thermochromic transition temperature in a time of less than about 5 seconds, a new low temperature color is generated which then has an irreversible thermochromic transition.
    • 热指示材料和在经历温度变化时能够进行热变色转变的材料的方法。 该材料包括具有以下结构的多种化合物:(I)其中R 1 -R 6 =氢,取代或未取代的烷基,取代或未取代的烷氧基 取代或未取代的芳基,取代或未取代的芳基,取代或未取代的烷基,取代或未取代的烷基,取代或未取代的酰基,取代或未取代的酯基, 未取代的芳基n为1至1000,m为0至1000,1为1至1000; 加入小分子,具有以下结构的小分子添加剂:R-Ar-R',RX,链烷烃或分子量小于1,000AMU的低聚环氧乙烷小分子,其中RR'=氢,取代或未取代的烷基 取代或未取代的烷基,取代或未取代的烷氧基,取代或未取代的烷硫基,取代或未取代的烷基硅烷基,取代或未取代的酰基,取代或未取代的酯基,取代或未取代的胺基, 包括但不限于苯,噻吩,萘,氟,蒽,吡啶,茚,联苯,菲和呋喃的取代或未取代的芳族或杂芳族基团X =卤素(F,Cl,Br, 或I)。 材料的热变色转变是可逆的。 热变色转变是两步转变,使得当样品被加热到热变色转变温度以上,然后在小于约5秒的时间内快速冷却至低于热变色转变温度的温度时,新的低温颜色为 然后产生不可逆的热变色转变。
