Organic thin-film transistors

A process of preparing a thin film transistor comprising:

• depositing a liquid composition onto a substrate to form a semiconducting layer, the liquid composition comprising a solvent, a polymer, and a halogen-coordinated metal phthalocyanine complex of Formula (I) or Formula (II):
• wherein M is a trivalent metal atom;
• each m represents the number of R substituents on the phenyl or naphthyl ring, and is independently an integer from 0 to 6;
• each R is independently selected from the group consisting of halogen, alkyl, substituted alkyl, alkoxy, substituted alkoxy, phenoxy, phenylthio, aryl, substituted aryl, heteroaryl, —CN, and —NO2;
• and
• X is a halogen atom.
