Abstract

Precise control over the electronic properties of carbon nanotubes is key to their application in plastic electronics. In the present work, we have functionalized carbon nanotubes with an electron withdrawing nonfluorinated olefins via a 2-2 cycloaddition reaction. Our results suggest that the formation of cyclobutanelike four-member ring at the functionalization site is a fairly general approach, independent of specifics of the addend, to converting the grown mixture of metal and semiconductor tubes into high mobility semiconducting tubes without tedious separation requirements. Thin film transistors fabricated from such functionalized tubes exhibit mobilities of ∼30 cm /V s and on/off ratios in excess of 10 . This simple functionalization represents a low cost path to high performance semiconducting inks for printable electronics. © 2010 American Institute of Physics. 2 6
