  Long-range exciton coupling from dipyrrinone chromophores

  摘要：

  Dipyrrinone chromophores, attached by their acid termini to give (1R,2R)-cyclohexanediol dipropionate and diacetate esters (xanthobilirubinate and nor-xanthobilirubinate, respectively), interact through exciton coupling, as evidenced by intense bisignate circular dichroism Cotton effects for the pigment's long wavelength transition. The bis-xanthobilirubinate exhibits the expected negative exciton chirality (DELTA-epsilon-439max -16, DELTA-epsilon-382max + 22, CH2Cl2) but the bis-norxanthobilirubinate exhibits positive exciton chirality (DELTA-epsilon-420max + 38, DELTA-epsilon-367max -46, CH2Cl2).
