BENZOPYRANS ANNELATED IN C7-C8 WITH AN AROMATIC HETEROCYCLE AND COMPOSITIONS AND (CO)POLYMER MATRICES CONTAINING THEM |
摘要 |
The invention relates to novel benzopyran-type compounds having an aromatic heterocycle annelated in position 7,8 and a carbocycle annelated in position 5,6. These compounds have formula (I). These compounds (I) have interesting photochromic properties. The invention also relates to their preparation, to their applications as photochromes, as well as to the compositions and (co)polymer matrices containing them.
