A　new　kind　of　photolabile　protecting　group　(PLPG)　for　carboxyl　moieties　was　designed　and　synthesized　as　the　linker　between　resin　and　peptide.　This　group　can　be　used　for　the　protection　of　amino　acid　carboxyl　groups.　The　peptide　was　synthesized　on　Nph　(2-hydroxy-3-(2-nitrophenyl)-heptanoic　acid)-derivatized　resins　and　could　be　cleaved　under　UV　exposure,　thus　avoiding　the　necessity　for　harsh　acid-mediated　resin　cleavage.　The　PLPG　has　been　successfully　used　for　solid-phase　synthesis　of　peptides.
