A technique for forming functionalized particles, where such particles are readily formed into periodic structures. A layer of particles is formed on a substrate, a first material is deposited over at least a portion of each of the particles, and then a functionalizing agent is attached to the first material. The functionalized particles are then capable of being formed into an ordered structure, by selection of appropriate complementary functionalizing agents on a substrate and/or on other particles and/or on other regions of the same particles.

Process for fabricating patterned, functionalized particles and article formed from particles

The invention relates to poly(phenylene vinylene) polymers substituted with dendritic sidechains to enhance main-chain separation in the solid state. The polymers are synthesized by the Heck polymerization and have a weight-average molecular weight of 20,000 to 60,000 Daltons. The polymers are self-ordering in the solid state and have thermotropic liquid crystalline phases. The polymers show enhanced photoconductivity, better charge transport capability and improved polarized light emission.

Polarizable photoactive and electroactive polymers and light emitting devices

An organic semiconducting material having bi-polar charge transport characteristics is described which may comprise the active layer of a field-effect transistor. The semiconducting material comprises a bi-polar polymeric film effective for hole or electron transport comprising a polymer having a conjugated framework with functional moieties capable of solvating ions or promoting ionic charge transport. The conjugated framework is selected from at least one of thiophene, pyrrole, benzene, naphthalene, antrhacene, and antrhacene-dione, and the functional moieties are selected from (i) functional side groups comprising salts of carboxylic acid and sulfonic acid and (ii) functional sites selected from heteroatoms having electron lone pairs comprising sulfur, nitrogen, and oxygen. The field-effect mobility of the bi-polar polymeric film is at least 10 cm /Vs when operating as an n-type or p-type device.
