通过增加铜酞菁(CuPc)溶液中三氟乙酸(TFA)的浓度,使铜酞菁发生质子化反应得到[CuPc·H]+和[CuPc·H2]2+两种衍生物,并用紫外可见分光光度计进行表征[CuPc·H]+和[CuPc·H2]2+两种衍生物的Q带相继发生红移.[CuPc·H]+和[CuPc·H2]2+两种衍生物的Q带都发生裂分,表明两种衍生物具有不对称结构.铜酞菁发生质子化反应后在有机溶剂中的溶解度增大了60倍,放置两周后不会发生降解.以发生质子化反应的铜酞菁溶液为电解液,用电沉积方法在ITO导电玻璃上制备铜酞菁薄膜并用扫描电镜(SEM)和X射线衍射(XRD)进行表征.在ITO基片上沉积的纳米CuPc薄膜,尺寸在100～200nm之间,具有α相晶体结构,分子的堆积方向(b轴)平行于基片.
By increasing the concentration of trifluoroacetic acid (TFA) in copper phthalocyanine (CuPc) solution, copper phthalocyanine was protonated to give two derivatives [CuPc · H] + and [CuPc · H2] 2+, The Q band of [CuPc · H] + and [CuPc · H2] 2+ derivatives were red-shifted one after the other with the spectrophotometer [CuPc · H] + and [CuPc · H2] 2+ Q band splitting, indicating that the two derivatives have asymmetric structure.Polyphthalocyanine after protonation in the organic solvent solubility increased by 60 times, place two weeks after the degradation will not occur in order to produce protonation The copper phthalocyanine solution was used as the electrolyte to prepare the copper phthalocyanine thin film on the ITO conductive glass by electrodeposition and characterized by SEM and XRD.The nano CuPc thin films deposited on the ITO substrate, Size between 100 ~ 200nm, with α-phase crystal structure, the molecular stacking direction (b axis) parallel to the substrate.
