在二氯甲烷(CH2Cl2)和三氟化硼二乙基醚(BFEE)二元溶液中,二苯基亚甲基荧烷(DPMF)直接阳极氧化合成了绿色发光聚二苯基亚甲基荧烯(PDPMF)。测得二甲基亚甲基四氢呋喃在该介质中的氧化电位仅为0.78nV,低于在0.1mol L−-1四丁基四氟硼酸铵(Bu_4NBF_4)作支持电解液的CH2Cl2(1.0nVvsAg/AgCl2)和乙腈(1.16nVvsAg/AgCl2)中的氧化电位。所制得的PDPMF薄膜具有良好的电化学行为和较高的热稳定性。荧光光谱表明,PDPMF是一种良好的绿光发射体,在365 nm紫外光下具有强烈的明亮的绿色或黄绿色光致发光。
Green-light-emitting poly(diphenylmethylenefluorene) (PDPMF) was synthesized electrochemically by direct anodic oxidation of diphenylmethylenefluorene (DPMF) in dichloromethane (CH2Cl2) and boron trifluoride diethyl etherate (BFEE) binary solution. The oxidation potential of DPMF in this medium was measured to be only 0.78 V versus Ag/AgCl, which was lower than that determined in CH2Cl2(1.0 V versus Ag/AgCl) or acetonitrile (ACN) (1.16 V versus Ag/AgCl) with 0.1 mol L−1tetrabutylammonium tetrafluoroborate (Bu4NBF4) as the supporting electrolyte. The as-formed PDPMF films showed good electrochemical behavior and high thermal stability. Fluorescent spectra indicate that PDPMF is a good green-light-emitter with strong and bright green or yellow-green photoluminescence under 365 nm UV light.
