Imide-functionalized　polycyclic　aromatic　hydrocarbons　(PAHs)　endow　fascinating　optoelectronic　properties,　rendering　them　suitable　for　many　applications.　Developing　these　new　kinds　of　functional　materials　is　interesting　and　challenging.　Dinaphtho[1,2-a:1　＇,2　＇-h]anthracene　(DNphA),　a　non-planar　S-shaped　double　helical　helicene　within　the　PAH　class,　has　received　relatively　little　research.　In　this　contribution,　a　series　of　solution-processable　DNphA　diimide　derivative　dyes　(M1　similar　to　M5)　were　designed　and　synthesized.　The　density　functional　theory　calculation,　photophysical　and　electrochemical　properties　of　the　new　fluorescent　dyes　have　been　investigated.　Notably,　M5　was　used　as　a　fluorescent　developer　for　latent　fingerprint　visualization,　where　fingerprints　on　different　substrates　displayed　clear　yellow-green　fluorescence.　This　research　provides　insights　into　the　efficient　design　strategy　of　the　imide　functionalization　of　DNphA　and　the　synthesis　and　application　of　DNphA　diimidebased　functional　dyes.
