A compound of formula
1
wherein Y represents a pyridyl group, or a phenyl group of formula
2
wherein R
3
represents a hydrogen atom, a CF
3
group or an alkoxy group, R
4
represents a hydrogen atom, an alkyl group, or a CF
3
group, R
5
represents a hydrogen atom, an alkyl group, a CF
3
group or an alkoxy group, and R
1
and R
2
are the substituents of a terminal alkene of formula
3
wherein R
1
represents an alkyl or alkylene group, a mono- or poly-cycloalkyl group, or a phenyl group that optionally includes one or several hetero-atoms of oxygen, nitrogen, phosphorous or sulfur; R
2
represents a hydrogen atom, an alkyl or alkylene group, a mono- or poly-cycloalkyl group, or a phenyl group that optionally includes one or several hetero-atoms of oxygen, nitrogen, phosphorous and sulfur. This compound is capable of releasing, upon an exposure to light, an active compound such as a perfume and can be advantageously used in the treatment of any surface in order to perfume it through the controlled release of a perfumed molecule.
式1的化合物,其中Y代表吡啶基团,或者式2的苯基团,其中R3代表氢原子、CF3基团或烷氧基团,R4代表氢原子、烷基团或CF3基团,R5代表氢原子、烷基团、CF3基团或烷氧基团,R1和R2是式3的末端烯烃的取代基,其中R1代表烷基或烷基烃基、单环或多环脂环基,或者可能包含氧、氮、磷或硫等一种或多种杂原子的苯基团;R2代表氢原子、烷基或烷基烃基、单环或多环脂环基,或者可能包含氧、氮、磷和硫等一种或多种杂原子的苯基团。该化合物能够在光照作用下释放活性化合物,如香水,并可以优势地用于处理任何表面,通过控制释放香水分子来使其带有香气。
