Organoboron compounds are described that upon exposure to light absorb light and isomerize and form a dark-colored isomer. The dark-colored isomer converts back to the colorless isomer upon removal of light, or exposure to oxygen or heat. Such compounds can be added into polymeric matrices such as films. These compounds are suitable for UV-blocking, UV-detecting, and for oxygen-sensing applications. Uses include UV-blocking windows, sunglasses, and as indicators in packaging such as food packaging.
描述了一种有机
硼化合物,当暴露于光线下时,会吸收光线并异构化形成深色异构体。深色异构体在去除光线或暴露于
氧气或热时会转化回无色异构体。这些化合物可以添加到聚合物基质中,如薄膜中。这些化合物适用于阻挡紫外线、检测紫外线和感知
氧气的应用。例如,用于阻挡紫外线的窗户、太阳镜,以及作为食品包装中的指示剂。
