摘要：
Novel side chain substituted Polythiophenes (PTs) are employed as active layers in sensing Organic Thin Film Transistors (OTFTs). Side chains functionalities on PT backbones have been chosen ad hoc in order to confer broad specificity towards analytes bearing homologous moieties. The electrical and sensing properties towards alcohol vapors are investigated. The sensors responses are evaluated from transient source-drain current and correlations between the chemical nature of the polymer side chain and the analyte functionality are discussed.
