合成了一种羧酸基取代的可溶性酞菁铜化合物，并对其光吸收性及导电性进行了研究。结果表明：（1）这种含有羧酸基的酞菁铜化合物在波长500～800nm有强吸收，较无取代基的酞菁铜化合物吸收波谱范围增宽；（2）该合成物具有一定的电导性，水解前化合物体电导率为10－7／Ω·cm，较无取代基的酞菁铜提高了4个数量级。水解后化合物表面电导率为10－2／Ω·cm；（3）随着电压的增加，羧酸基取代酞菁铜薄膜的电流和表面电导率提高，并出现了一个突跃点；随着温度的提高，薄膜的电导率也增高。
A carboxylic acid-substituted soluble copper phthalocyanine compound was synthesized and its optical absorption and electrical conductivity were studied. The results show that: (1) The copper phthalocyanine compounds with carboxylic acid groups have strong absorption at 500-800 nm, broaden the absorption spectrum of the phthalocyanine compounds without substituents. (2) Conductivity, before the hydrolysis of the compound body conductivity of 10-7 / Ω · cm, compared with non-substituted copper phthalocyanine increased 4 orders of magnitude. After the hydrolysis, the surface conductivity of the compound is 10-2 / Ω · cm. (3) With the increase of voltage, the current and surface conductivity of carboxylic acid substituted copper phthalocyanine films increase and there is a sudden jump; The temperature increases, the conductivity of the film also increased.
