Novel low voltage and solution processable organic thin film transistors based on water dispersed polymer semiconductor nanoparticulates

Colloids of semiconducting polymers for high-performance, environment-friendly polymer field effect transistors

“…Note that the mobility values obtained from the BA-based PFETs are quite close to the realistic minimum requirement for driving FETs of commercial organic light emitting diodes [20]. To the best of our knowledge, the present mobility values are the highest among those of PFETs processed using relatively green solvents [5][6][7].…”

“…In the field of semiconducting polymers, however, efforts to fabricate polymer colloids to meet the trend toward greener polymer technologies have been limited [5][6][7]. This can be attributed in part to the fact that the colloids of semiconducting polymers usually exhibit very low charge carrier mobility.…”

“…This can be attributed in part to the fact that the colloids of semiconducting polymers usually exhibit very low charge carrier mobility. For example, Zhou and coworkers demonstrated that colloids of poly-3(-hexylthiophene) could be dispersed in water either with or without the assistance of a surfactant, and relatively higher mobility was obtained from the colloids without surfactant, presumably due to better interparticle charge transport [7]. Although this result is very interesting, the mobility was still remarkably low compared to that of bulk poly-3(-hexylthiophene).…”

Organic Bioelectronics: Materials and Biocompatibility

“…The key considerations for biosensors is the ability to use them for aqueous analytes (e.g., blood, saliva) without triggering any unwanted electrochemical reactions, analyte specificity and sensitivity. Furthermore, low power consumption [108], low-cost and facile fabrication are desired to maximize commercial potential. As such, the printability and low-cost nature of organic electronic devices is highly advantageous [109].…”

The effect of mesomorphology upon the performance of nanoparticulate organic photovoltaic devices

“…More importantly, the nanoparticulate structure offers the opportunity to control the semi-conducting polymer and blend morphology on the nanoscale [3,4]. Consequently, NP organic thin films are increasingly finding application in areas such as thin film transistors [5], light-emitting diodes [6], and in particular photovoltaics [7,8] where roll to roll printing of NP OPV devices has been demonstrated [9,10] and power conversion efficiencies (PCEs) of up to 2.5% have already been achieved for small area devices [11].…”
