제목 Synthesis of Pull-type Phenazine units for Polymer Solar Cells
초록 The new phenazine unit for polymer solar cells was synthesized by various methods. The initial meterials 1,4-bis(dodecyloxy)-7,8-difluoro-2,3-dimethylphenazine and 1,4-bis(dodecyloxy)-7,8-difluorophenazine-2,3-dicarbonitrile were synthesized by the coupling reaction of bromine with amine using Ruphos Pd G2 catalyst. However, in the next step, the bromination reaction to substitute bromine on both sides of the material did not proceed due to steric hindrance. Due to this problem, molecular design has been improved, and the coupling reaction is initiated after bromide has been replaced in the reactants. The reactants were coupled to using 2,5-dihydroxy-1,4-benzoquinone with 3,6-dibromo-4,5-difluorobenzene-1,2-diamine, respectively, and the final material (DBDFPz) was synthesized via alkylation and stille reactions.
