溶液プロセスによるデバイス化を目指した可溶性トリオキソトリアンギュレンの合成

Abstract

Novel trioxotriangulene (TOT) type stable neutral radicals with high solubility in organic solvents were synthesized with aim of new type liquid-phase secondary battery and solution-processed semiconductive devices such as photo voltaic cells. Benzene-rings having three alkoxy groups were introduced at the 2，6，10-positions of TOT skeleton via the cross-coupling reaction of the radical precursor of brominated TOT. These TOT derivatives were soluble to several organic solvents such as CH[2]Cl[2] and toluene， etc. The stereoelectronic effiects of substituent groups on the redox properties were investigated by the cyclic voltammetry. The electronic-spin structures were elucidated by the ESR spectra and sophisticated quantum chemical calculation.
