Diglycidyl ether of 4,4'-(9-fluorenylidene)diphenol (DGEFDP) was prepared by the reaction of 4,4'-(9-fluorenylidene)diphenol and epibromohydrin by using NaOH aqueous solution. DGEFDP film showed characteristic UV-visible absorption band at 313nm and PL maximum values of 369 and 426nm corresponding to the photon energy of 3.36 and 2.91 eV at 313nm excitation. This compound exhibited deep-blue fluorescence on TLC plate. The cyclovoltamograms of DGEFDP exhibited the irreversible electrochemical behaviors between the doping and undoping peaks. The oxidation current density of DGEFDP versus the scan rate is approximately linear relationship in the range of 30 similar to 150mV/sec. The exponent of scan rate, x value of DGEFDP, was 0.401, which means that the kinetics of the redox process is mainly controlled by the reactant diffusion process.
