Asymmetrical bisbenzotriazoles of the formula I
where G2′ is perfluoroalkyl of 1 to 12 carbon atoms, preferably CF3, and where G2 does not contain said group are red-shifted and due to the asymmetry are particularly soluble and useful in a host of applications including automotive coatings, thermoplastics and especially in adhesive compositions, themselves useful in solar panels and other laminate structures.
公式I中的不对称双苯并三唑,其中G2′是1至12个碳原子的
全氟烷基,优选
CF3,而G2不含该基团,这些物质发生红移,由于不对称性,它们在许多应用中特别溶解且有用,包括汽车涂料、热塑性塑料,特别是在粘合剂组合物中,这些组合物本身在太阳能电池板和其他层压结构中有用。
