Abstract

フルオロ基, チオフェニル基, チオブチル基を導入した異方性をもたないサブフタロシアニン誘導体6種類を合成し, サイクリックボルタンメトリー, 紫外可視吸収スペクトル, 蛍光スペクトルの測定結果から電気化学的および分光学的特性を検討した。<BR>紫外可視吸収スペクトルにおいて, 置換基を導入したサブフタロシアニン誘導体は無置換サブフタロシアニンよりも吸収極大ピークが長波長側にシフトし, フタロシアニン誘導体と同程度の吸収極大波長を示した。通常のフタロシアニンよりもサブフタロシアニンは低分子量の非平面であるため置換基による影響が大きいと考えられる。

Six types of subphthalocyanine derivatives having fluoro, thiobutyl and thiophenyl substituents were synthesized. Their electrochemical and spectroscopic properties were studied from the results of cyclic voltammetry and UV-vis absorption and fluorescent spectroscopies.<BR>In the absorption spectra of the subphthalocyanine derivatives having the substituents, absorption maxima shifted to longer wavelength in comparison with nonsubstituted subphthalocyanine. Absorption maxima for the substituted subphthalocyanine were close to that for phthalocyanine. From the result of the intensity of absorption maxima in UV-vis spectra, it was suggested that the non-planer framework of subphthalocyanine molecule turns into the planer structure by the introduction of electrophilic substituents. Since molecular weight of the subphthalocyanine derivatives was smaller than that of normal subphthalocyanine, the effect of substituent on electron density for the subphthalocyanine derivatives was thought to be greater.
