摘　　要：Acenapththylene-imide(An I),similar to naphthalene diimide(NDI),is an outstanding building block for organic functional materials and has gained a lot of research attention.Herein,Sulphur and Selenium-embedded AnI-containing polycyclic aromatic hydrocarbon molecules,AnI-SQ and AnI-SeQ,with[1,2,5]thiadiazolo[3,4-g]quinoxaline(SQ)and[1,2,5]selenadiazolo[3,4-g]quinoxaline(Se Q)are designed and synthesized with low-lying LUMO energy levels.The absorption and emission of AnI-SQ and An I-Se Q displayed a bathochromic shift upon protonation of the C=N bond.Besides,theoretical calculation indicates remarkable rigid planar backbones for both An I-SQ and An I-Se Q.Through self-assembly with polymeric Pluronic?F-127,corresponding hydrophilic nanoparticles(NPs)were prepared with low cytotoxicity.And AnI-SQ NPs could be applied for in vitro two-photon fluorescence imaging.
