    摘要: Graft polymers such as grafted polyacetylene and devices based on derivatives of these polymers are produced utilizing a specific process. The process includes the steps of polymerizing a monomer such as acetylene in the presence of a host polymer such as polyisoprene to produce a graft polymer. The use of a host polymer yields several desirable results. For example, when the graft polymerization is performed in the presence of a solvent for an appropriate host polymer, the entire graft polymer is solvated. The solvated graft polymer is then employable to produce films of polymers on a substrate which are in turn useful in structures such as devices.

    摘要: Poly(glycolide) polymers are disclosed. The polymers generally include a polymerized alkynyl-substituted glycolide having a polymer backbone with one or more alkynyl groups appended thereto. The alkynyl groups provide reactive sites for further functionalization of the polymer, for example by reaction with azide derivatives (e.g., azide-substituted organic compounds). Alkynyl and azide groups react via the “click” chemistry mechanism to form functional groups covalently bonded to the polymer via a triazole link. The polymers are biodegradable and can be used to deliver drugs or other therapeutic substances (e.g., large biomolecules such as single strand RNA) at targeted locations in a patient's body and/or at controlled release rates.

    摘要: Poly(glycolide) polymers are disclosed. The polymers generally include a glycolide-based polymer backbone that includes one or more functional groups such as alkynyl groups, hydrophilic organic triazole groups, hydrophobic organic triazole groups (also including amphiphilic organic triazole groups), di-triazole organic crosslinking groups, and triazole-substituted drug derivatives. The alkynyl groups provide reactive sites for further functionalization of the polymer, for example by reaction with azide derivatives. The polymers can further encapsulate a drug for delivery to a patient (i.e., as compared to drug derivatives that are covalently attached to the polymer). The polymers can be in the form of thermodynamically stable unimolecular micelles or crosslinked nanoparticles. The polymer compositions are completely biodegradable and hold great potential for use in biomedical applications.

    摘要: Novel optical waveguides and methods for their fabrication are provided. The waveguides are made from polydiacetylene materials. The waveguides are made by a bilayer process wherein a film made from a soluble polydiacetylene material is applied to a substrate and a silicon-containing imaging layer is applied atop the polyacetylene layer. Thereafter a pattern is produced in the imaging layer, for example, by photolithographic methods, and the pattern is transferred to the underlying polydiacetylene layer by exposure to an oxygen plasma. Polydiacetylene waveguides greater than 0.4 microns thickness are thereby produced.

    摘要: A channel waveguide structure comprises a substrate, a channel pattern defined in the substrate adjacent the top surface of the substrate, and a planar film layer on top substrate. The channel pattern comprises channels having a high index of refraction, while the film layer is made from a nonlinear organic material. In a preferred embodiment, the substrate is glass and the channel pattern comprises ion-exchanged channels. In this preferred embodiment, the nonlinear organic material is a soluble polydiacetylene, such as poly(3BCMU), poly(4BCMU), or poly(TS12). The thicknesses of the ion-exchanged channels and of the film layer can be adjusted so that the channel waveguide structure functions as a single mode waveguide for light having a wavelength in the range of 1.3 to 1.67 microns.
