摘      要：The perylene diimide derivatives（s-THBPDI and d-THBPDI） bearing oxygen bridged twisty heptatomic biphenyl in the bay positions of the perylene core through acetylene bond were designed and *** photophysical properties of the functionalized dyes were investigated in solution and solid state by UV-vis and photoluminescence（PL） *** UV-vis and PL spectrum both exhibited the different concentration-dependent behaviors due to the difference of chemical ***,cyclic voltammetry results indicated that the introduction of oxygen bridged twisted heptatomic biphenyl could decrease the LUMO energy level of the perylene diimide effectively and made it promising material in photoelectric devices.
