One of most recommended methods for the detection of CWAs is the semiconducting device. There are two main types of semiconducting devices Sn02 and ZnO. Among Sn02 devices, there are several different types which can be differentiated according to the thickness and size, such as thick-film, thin-film, and micro. Although different, these types of sensor actually have...

Electrodes of two-dimensional sheet polymers of phthalocyanines prepared by in situ reaction of tetracyanobenzene with thin metal films were prepared and characterized in their photoelectrochemical characteristics. Anodic photocurrents were detected, characterizing these films as n-type semiconducting materials. It was also found that such films could be reduced at more positive potentials than unsubstituted phthalocyanines. This change when compared to films of divalent unsubstituted phthalocyanines is caused by unreacted CN groups that were found in the films " . Such films therefore can be looked at as substituted phthalocyanines with electron-withdrawing CN groups which explains their photoelectrochemical characteristics.
