Abstract
- Langmuir–Blodgett (LB) films of tert -butyl-substituted copper azaporphyrines, namely binuclear phthalocyanine (Cu 2 Pc 2 ’) and porphyrazine (CuPaz’), were formed from the floating layers differently structured. Effect of the film structure on sorption of benzene and hexane by the LB films was studied microgravimetrically. The greatest benzene/hexane selectivity was found for the homogeneous film of Cu 2 Pc 2 ’.
