Abstract

In this paper, europium bisphthalocyanine derivative (EuPc2′) LB films transferred to an interdigital electrode have been prepared at room temperature. The dynamic response of the electrical conductance to Cl2 gas is presented. At room temperature, the response time of 10-layer LB films of EuPc2′ is 45 s and the recovery time is 1 min after exposure to a concentration of 50 ppm Cl2. The reproducibility of the conductivity changes can be ...
