Circularly polarized luminescence based on cholesterol-tetraphenylethylene-perylene liquid crystal
文献摘要:
Perylene derivative with circularly polarized luminescence(CPL)at aggregated state was seldom re-ported due to the strong ACQ(aggregation-caused quench)effect at aggregation.In this work,a novel cholesterol-tetraphenylethylene-perylene derivative(TPE-P)was designed and synthesized in moderate yield.It exhibited liquid crystalline behavior with orderly hexagonal columnar mesophase and good flu-orescence emission at long wavelength(600-700 nm)not only in solution but also at aggregated states based on the AIE(aggregation-induced emission)-FRET(fluorescence resonance energy transfer)effect between tetraphenylethylene unit and perylene moiety.Moreover,the circular dichroism(CD)and CPL studies suggested the effective chiral transfer from cholesterol unit to tetraphenylethylene unit and pery-lene skeleton due to the spiral liquid crystalline self-assembly.The CD and CPL signals showed the order of THF<THF-hexane<solid film<meosphase,indicating that the higher spiral orderly degree resulted in the stronger chiral transfer.The largest|glum|value for mesophase excited at 320 nm was as high as 1.5×10-2 based on the combining effect of AIE-FRET and chiral transfer.This research not only reported a novel CPL perylene derivative at aggregated state,but also confirmed that the combination of AIE-FRET effect and chiral transfer of liquid crytalline phase was an effective method to construct normal dye with excellent CPL property in aggregated state.
