title: Thio-bisnaphthalimides as Heavy-Atom-Free Photosensitizers with Efficient Singlet Oxygen Generation and Large Stokes Shifts: Synthesis and Properties.
abstract: By structure transformation of benzo[k,l]thioxanthene-naphthalimide derivatives (ND-S), a novel series of nonplanar thio-heterocyclic bisnaphthalimide derivatives are designed and synthesized. They display high molar absorptivity and large Stokes shifts. They are also heavy-atom-free photosensitizers with high singlet oxygen quantum yields of 0.75 and 0.82. Thus, these new structures based on the naphthalimide skeleton have great potential for singlet oxygen applications.
