Properties of multi-functional polymers containing terbium complex

A kind of multi-functional polymer P1 containing terbium complex was synthesized by free radical polymerization. The chemical composition was analyzed by elemental analysis and XPS, and the structure was confirmed. The fluorescence property was investigated in solid state. The result indicated that the dominant emission was from D-5(4)-->F-7(5) of the terbium complex at about 543 nm and with a bandwidth of less than 10 nm, a pure green light. The electrochemical property was studied, and the HOMO and LUMO energy levels were obtained by cyclic voltammetry(CV) methods. The CV result indicated that the HOMO and LUMO energy levels of P1 matched well the respective work function of ITO (-4.80 eV) and Ca (-2.89 eV). The CV result also revealed that the polymer P1 had the ability to balance the hole transport and electron transport.
