    • The invention relates to a method for modifying the absorption of electromagnetic radiation by one or more compounds of general formula (I) or (II), wherein these compounds are irradiated with electromagnetic radiation of a wavelength of 300 to 750 nm. The invention further relates to the use of compounds of general formula (I) or (II) for marking material, e.g. paper or mineral oil and to the use of compounds of general formula (I) or (II) for causing a color change. The invention also relates to the use of compounds of general formula (I) or (II) in laser welding, heat management, as photoinitiator, as radical scavenger or for detecting oxygen. The invention relates to a method for controlling the absorption or transmission of electromagnetic radiation by a material, one or more of the compounds of general formula (I) or (II) being contacted with said material and the compounds being irradiated with electromagnetic radiation having a wavelength of 300 to 750 nm. The invention finally relates to specific compounds of general formula (I).
    • 由(I)或(II)的通式的一种或多种化合物,其中这些化合物照射的300至750nm波长的电磁辐射改变电磁辐射的吸收的方法。 用于材料,如纸或矿物油,和使用通式(I)或(II)以引起颜色变化的化合物的标记的通式(I)或化合物的用途(II)。 使用通式(I)或(II),用于激光焊接,热管理,作为光引发剂,如清除剂或用于检测氧气的化合物。 一种用于由材料调节吸收或电磁辐射的传输,其中,所述通式(I)或(II)的一种或多种化合物相接触用这种材料和这些化合物与的300至750nm波长的电磁辐射照射方法。 通式(I)的具体化合物。
