摘要：
Fragrances that provide a scent of freshness tend to be volatile and are therefore not very economical when used in typical applications such as washing or cleaning processes, so they have to be used in relatively large quantities to be able to produce adequate effects. The disclosed photolabile pro-fragrances provide a much longer-lasting sense of fragrance, in particular with a scent of freshness, when used in typical applications, thus allowing said fragrances to be used economically.
