Novel phenylenevinylene oligomers substituted with crown ether rings (CE-OPV) were synthesized using a Wittig or Horner-Wadsworth-Emmons reaction. The resulting oligomers give strong fluorescence emission at 515 nm with a quantum efficiency of ca. 80% in MeCN. While light-emitting diodes (LEDs) with the structure ITO/CE-OPV/Al show similar emission to the photoluminescence at a relatively high turn-on voltage of ca. 9 V/100 nm, the corresponding light-emitting electrochemical cells (LECs) with the structure ITO/CE-OPV + LiCF3SO3/Al emit bluish-green light at a rather low turn-on voltage of ca. 3 V for both the forward and reverse bias. These results indicate that the chemically-grafted crown ether rings assist ionic conductivity, and thus the CE-OPV is of promise for LEC applications.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 14098-44-3 is helpful to your research., Reference of 14098-44-3
