    摘要： The present invention is directed to methods of separating carbon nanotubes (CNTs) by their electronic type (e.g., metallic, semi-metallic, and semiconducting). Perhaps most generally, in some embodiments, the present invention is directed to methods of separating CNTs by bandgap, wherein such separation is effected by interacting the CNTs with a surface such that the surface interacts differentially with the CNTs on the basis of their bandgap, or lack thereof. In some embodiments, such methods can allow for such separations to be carried out in bulk quantities.

    摘要： The invented ink-jet printing method for the construction of thin film transistors using all SWNTs on flexible plastic films is a new process. This method is more practical than all of exiting printing methods in the construction TFT and RFID tags because SWNTs have superior properties of both electrical and mechanical over organic conducting oligomers and polymers which often used for TFT. Furthermore, this method can be applied on thin films such as paper and plastic films while silicon based techniques can not used on such flexible films. These are superior to the traditional conducting polymers used in printable devices since they need no dopant and they are more stable. They could be used in conjunction with conducting polymers, or as stand-alone inks.

    摘要翻译： 本发明的用于在柔性塑料薄膜上构造使用所有SWNT的薄膜晶体管的喷墨打印方法是一个新的过程。 该方法比建筑TFT和RFID标签中的所有现有印刷方法更实用，因为SWNT具有优于常用于TFT的有机导电低聚物和聚合物的电和机械性能。 此外，该方法可以应用于诸如纸和塑料膜的薄膜上，而基于硅的技术不能用于这种柔性膜。 它们优于用于可印刷装置的传统导电聚合物，因为它们不需要掺杂剂并且它们更稳定。 它们可以与导电聚合物一起使用，或者作为独立的油墨使用。

    摘要： The invention incorporates new processes for the chemical modification of carbon nanotubes. Such processes involve the derivatization of multi- and single-wall carbon nanotubes, including small diameter (ca. 0.7 nm) single-wall carbon nanotubes, with diazonium species. The method allows the chemical attachment of a variety of organic compounds to the side and ends of carbon nanotubes. These chemically modified nanotubes have applications in polymer composite materials, molecular electronic applications, and sensor devices. The methods of derivatization include electrochemical induced reactions, thermally induced reactions (via in-situ generation of diazonium compounds or pre-formed diazonium compounds), and photochemically induced reactions. The derivatization causes significant changes in the spectroscopic properties of the nanotubes. The estimated degree of functionality is ca. 1 out of every 20 to 30 carbons in a nanotube bearing a functionality moiety. Such electrochemical reduction processes can be adapted to apply site-selective chemical functionalization of nanotubes. Moreover, when modified with suitable chemical groups, the derivatized nanotubes are chemically compatible with a polymer matrix, allowing transfer of the properties of the nanotubes (such as, mechanical strength or electrical conductivity) to the properties of the composite material as a whole. Furthermore, when modified with suitable chemical groups, the groups can be polymerized to form a polymer that includes carbon nanotubes.

    摘要： The present invention incorporates new processes for blending derivatized carbon nanotubes into polymer matrices to create new polymer/composite materials. When modified with suitable chemical groups using diazonium chemistry, the nanotubes can be made chemically compatible with a polymer matrix, allowing transfer of the properties of the nanotubes (such as mechanical strength) to the properties of the composite material as a whole. To achieve this, the derivatized (modified) carbon nanotubes are physically blended with the polymeric material, and/or, if desired, allowed to react at ambient or elevated temperature. These methods can be utilized to append functionalities to the nanotubes that will further covalently bond to the host polymer matrix, or directly between two tubes themselves. Furthermore, the nanotubes can be used as a generator of polymer growth, wherein the nanotubes are derivatized with a functional group that is an active part of a polymerization process, which would also result in a composite material in which the carbon nanotubes are chemically involved.

    摘要： The present invention is a design paradigm for molecular scale electronic systems wherein electronic information is transmitted and processed, and electronic logic is obtained by changing the electrostatic potential of a molecule. The signal may be restored using an external potential through the underlying substrate. Several convergent synthetic routes are shown to conjugated molecules with various potential electronic device applications including a two-terminal molecular wire with a transport barrier, a molecular wire with two transport barriers, three-terminal junctions, three-terminal structures with switch-like possibilities, and four-terminal systems that could serve as logical gates without the use of multiple transistors. Ab initio computational methods are used to show that (i) molecules can be considered active electronic devices able to transfer the information from one molecule to another, (ii) the electrostatic potential can also be used as a tool to perform logical operations, and (iii) that the molecules synthesized here could perform the functions for which they were designed.
