13 Wei, J., Wang, B. A highly efficient polymerizable photoinitiator comprising benzophenone, thio moieties, and n-arylmaleimide. So design, synthesis and photoinitiation activity study of novel benzophenone derivatives obviously become an important subject. Comment With the advantages of simple synthesis and low price, benzophenone derivatives were widely used in the areas of photoinitiator [[4]], sunscreen [[5]], [[6]], [[7]], photoluminescent materials [[8]], organic field-effect transistor [[10]], pesticide [[11]] and so on.
