    Abstract: Embodiments described herein relate to compositions including iptycene-based structures. Some embodiments provide compositions including polymers having a backbone comprising an iptycene-based compound. Some embodiments described herein provide compositions having enhanced properties such as enhanced porosity, increased glass transition temperatures, and/or improved solubility as compared to traditional poly(aryl ether)-based compounds or traditional iptycene-based compounds. In some cases, the compositions may include various aryl ether compounds such as an aryl ether ketone incorporated into the polymer backbone. Non-limiting examples of suitable aryl ether compounds include polyaylethersulfones, polyaryletherketones, polyetherimides, and polyphenylene ethers. The compositions described herein may be useful in a wide variety of applications, including structural materials, flexible composites, ion conductors, fuel cell membranes such as proton exchanging membranes, sensors, preconcentrators, absorbents, or the like.

    Abstract: The present invention generally relates to emissive materials, devices, and related methods. In some cases, the present invention provides sensors and methods for the determination of analytes, wherein the analytes may be determined by monitoring, for example, a change in an optical signal of an emissive material upon exposure to an analyte.The analyte and the emissive material may interact via a chemical reaction, such as an oxidative addition reaction, or other chemical, biochemical or biological interaction (e.g., recognition), to form a new emissive species. In some cases, the present invention may be useful in the detection of a wide variety of analytes, such as toxins, chemical warfare agents, and explosives. The present invention also provides emissive compounds, and related methods, including metal complexes that are capable of interacting with an analyte to produce a change in the emission of the compound. Some advantages of the present invention include the determination of analytes with high specificity and sensitivity and the ability to fabricate simplified and highly portable devices.

    Abstract: Embodiments described herein generally relate to compositions including discrete nanostructures (e.g., nanostructures including a functionalized graphene layer and a core species bound to the functionalized graphene layer), and related articles and methods. A composition may have a coefficient of friction of less than or equal to 0.02. Discrete nanostructures may have a substantially non-planar configuration. A core species may reversibly covalently bind a first portion of a functionalized graphene layer to a second portion of the functionalized graphene layer. Articles, e.g., articles including a plurality of discrete nanostructures and a means for depositing the plurality of discrete nanostructures on a surface, are also provided. Methods (e.g., methods of forming a layer) are also provided, including depositing a composition onto a substrate surface and/or applying a mechanical force to the composition, e.g., such that the composition exhibits a coefficient of friction of less than or equal to 0.02.
