The present invention provides use of penta-substituted tetrahydropyrimidines in preparation of thermo-sensitive fluorescent materials. Said penta-substituted tetrahydropyrimidine compounds have linear temperature dependence of red-edge excitation wavelength (LTDREEW). When different excitation wavelengths are chosen, such compounds present fluorescence color and/or fluorescence on-off switch in different temperature ranges. Also their fluorescence intensity ratios or fluorescence intensities exhibit good linear relation or power function relation to temperature, which can be used as the thermo-sensitive fluorescent materials with high sensitivity and wide temperature range (0-450 K).
本发明提供了五取代四氢
嘧啶在制备热敏荧光材料中的应用。所述五取代四氢
嘧啶化合物的红边激发波长(LTDREEW)具有线性温度依赖性。当选择不同的激发波长时,这些化合物在不同的温度范围内呈现出不同的荧光颜色和/或荧光开关。此外,它们的荧光强度比或荧光强度与温度呈良好的线性关系或幂函数关系,可用作具有高灵敏度和宽温度范围(0-450 K)的热敏荧光材料。
