Thin films of non-covalently hybridized single-walled carbon nanotubes (SWCNT) and tetra-substituted copper phthalocyanine (CuPcR4) molecules have been produced from their solutions in dimethylformamide (DMF). FTIR spectra revealed the 7π-7π interaction between SWCNTs and CuPcR4 molecules. DC conductivity of films of acid-treated SWCNT/CuPcR4 hybrid has increased by more than three orders of.magnitude in comparison with conductivity of CuPcR4 films. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) measurements have shown that films obtained from the acid-treated SWCNTs/CuPcR4 hybrids demonstrated more homogenous surface which is ascribed to the highly improved solubility of the hybrid powder in DMF Using total internal reflection ellipsometry spectroscopy (TIRE), thin films of the new hybrid have been examined as an optical sensing membrane for the detection of benzo[a]pyrene in water to demonstrate the sensing properties of the hybrid.
通过将非共价杂交的单壁碳纳米管（SWCNT）和四取代铜酞菁（CuPcR4）分子溶解在二甲基甲酰胺（DMF）中，制备出了它们的薄膜。傅里叶变换红外光谱（FTIR）显示SWCNT与CuPcR4分子之间存在7π-7π相互作用。与CuPcR4薄膜的电导率相比，酸处理的SWCNT/CuPcR4杂化薄膜的直流电导率增加了三个多数量级。扫描电子显微镜（SEM）和原子力显微镜（AFM）测量表明，由酸处理的SWCNT/CuPcR4杂化物制备的薄膜具有更均匀的表面，这归因于杂化粉末在DMF中的溶解度大大提高。使用全内反射椭圆偏振光谱法（TIRE），对新型杂化物的薄膜作为检测水中苯并[a]芘的光学传感膜进行了检测，以证明该杂化物的传感特性。
