摘要： A composition for use in a photo-active device has: a charge transfer network of single walled carbon nanotubes (SWCNT) having at least 95 wt% of semiconducting single walled carbon nanotubes (sc-SWCNT) based on total weight of the SWCNT, the sc-SWCNT containing at least 30 wt% of one chiral type of sc-SWCNT based on total weight of the sc-SWCNT; and, a solution processible electron trapping material of a fullerene compound, the electron trapping material in contact with the charge transfer network of SWCNT. The composition is readily prepared from solution processible components and is highly sensitive in a narrow wavelength band. The composition is particularly useful in photoconductors and phototransistors that operate on the infrared region of the electromagnetic spectrum.

摘要： A process for purifying semiconducting single-walled carbon nanotubes (sc- SWCNTs) extracted with a conjugated polymer, the process comprising exchanging the conjugated polymer with an s-tetrazine based polymer in a processed sc-SWCNT dispersion that comprises the conjugated polymer associated with the sc-SWCNTs. The process can be used for production of thin film transistors and chemical sensors. In addition, disclosed herein is use of an s-tetrazine based polymer for purification of semiconducting single-walled carbon nanotubes (sc-SWCNTs).

摘要： A two-step sc-SWCNT enrichment process involves a first step based on selective dispersion and extraction of semiconducting SWCNT using conjugated polymer followed by a second step based on an adsorptive process in which the product of the first step is exposed to an inorganic absorptive medium to selectively bind predominantly metallic SWCNTs such that what remains dispersed in solution is further enriched in semiconducting SWCNTs. The process is easily scalable for large-diameter semi- conducting single-walled carbon nanotube (sc-SWCNT) enrichment with average diameters in a range, for example, of about 0.6 to 2.2 nm. The first step produces an enriched sc-SWCNT dispersion with a moderated sc-purity (98%) at a high yield, or a high purity (99% and up) at a low yield. The second step can not only enhance the purity of the polymer enriched sc-SWCNTs with a moderate purity, but also further promote the highly purified sample to an ultra-pure level. Therefore, this two-step hybrid process provides sc-SWCNT materials with a super high purity, as well as both a high sc-purity (for example greater than 99%) and a high yield (up to about 20% or higher).
摘要翻译：两步sc-SWCNT富集方法包括基于使用共轭聚合物的半导体SWCNT的选择性分散和萃取的第一步骤，然后基于吸附过程的第二步骤，其中第一步骤的产物暴露于无机吸收介质以选择性地结合主要金属的SWCNT，使得在溶液中分散的物质进一步富集在半导体SWCNT中。该方法可以容易地扩展到大直径半导体单壁碳纳米管（sc-SWCNT）富集，其平均直径在例如约0.6至2.2nm的范围内。第一步以高产率或高纯度（99％及以上）以低产率产生具有缓和sc-纯度（98％）的富集的sc-SWCNT分散体。第二步不仅可以提高中等纯度的富集聚合物的sc-SWCNT的纯度，还可以进一步促进高纯度样品达到超纯水平。因此，这种两步混合工艺提供具有超高纯度的sc-SWCNT材料，以及高sc纯度（例如大于99％）和高产率（高达约20％或更高）两者。

摘要： The present application relates to thin film transistors having a semiconducting channel comprising a network of carbon nanotubes that are electrically coupled to a source electrode and a drain electrode and electrically insulated from, but capacitively coupled to, a gate electrode, wherein a polymeric layer encapsulates the carbon nanotubes. The polymeric layer can comprise a first monomeric unit and optionally a second monomeric unit, wherein the first monomeric unit, the second monomeric unit and the relative amounts thereof are optionally selected to provide at least one target electrical property of the thin film transistor. The present application also relates to methods for manufacturing such thin film transistors as well as a methods of selecting a polymeric layer to provide a desired threshold voltage for such thin film transistors.

摘要： A single-walled carbon nanotube composition includes single-walled carbon nanotubes substantially enriched in semiconducting single-walled carbon nanotubes in association with a polymer having one or more oligoether side groups. The oligoether side groups render the composition dispersable in polar organic solvents, for example alkyl carbitols, permitting formulation of ink compositions containing single-walled carbon nanotubes substantially enriched in semiconducting single-walled carbon nanotubes. Such ink compositions may be readily printed using common printing methods, such as inkjet, flexography and gravure printing.
