The performance of organic semiconductor field-effect transistor has been improved tremendously in the last few years, focusing on increasing the environmental stability and charge carrier mobility of p- and n-type polymers and small molecules. In particular, for polymers the record mobility values reported till date are approaching 2cm (V s ) for p-type polymers [7] and Icm (V s ) for n-type polymers [8]. The p-type conduction has been till last few years much superior than n-type one, due to the oxygen and water sensitivity of many organic anions [9]. Only recentiy, n-type polymers with comparable performance have been reported.

As a class of n-type organic semiconductors, PBI derivatives have received considerable attention for a variety of applications [312, 313], for example, for organic or polymer light-emitting diodes (OLEDs and PLEDs) [314, 315], thin-film organic field-effect transistors (OFETs) [316, 317], solar cells [318, 319], and liquid crystals [320]. They are also interesting candidates for single-molecule device applications, such as sensors [321], molecular wires [322], or transistors [141].

A main focus of preparing metal dithiolenes functionalized with thiophene units has been for their incorporation into conjugated organic materials. On first glance, it would seem that the combination of metal dithiolenes and conjugated polymers could produce attractive new materials for use in such applications as field effect transistors and NIR optical materials. However, several challenges remain before these materials can be applied to useful... 

Our choice for an Ion Sensitive Field Effect Transistor (ISFET) as a transducing element was based on the fact that the SiO surface contains reactive SiOH groups for the covalent attachment of organic molecules and polymers. In addition the FET has fast response times and can be made very small with existing planar IC technology. FIGURE 1...
