A semiconductor sensor device for detecting an analyte including a semiconducting layer, one or more organic molecules in the semiconducting layer, and one or more receptor molecules, comprising a poly-cyanostilbene macrocycle, wherein the one or more receptors is embedded within or onto the semiconducting layer of the semiconductor sensor device. Also disclosed is a method of preparing the semiconductor sensor device including a step of coupling the one or more receptor molecules into or onto the semiconducting layer of the semiconductor sensor device, a dielectric surface, or an electrode surface. Also described is chemical sensing device including the semiconductor sensor device and other elements of a sensing device.

Macrocycle embedded organic electronic materials, composites, and compositions for chemical sensing

The methods disclosed utilize &#x3c0;-conjugated polymers (CPs) as sensors for various analytes through the inner filter effect (IFE). Further, the methods utilize CPs with controlled optical properties for targeting sensing applications and operates through a novel IFE-based method, providing sensitive and selective sensors that operate in complex environments. The methods further provide calibration standards for the identification of similar and structurally distinct target analytes, where the analyte is a small molecule, macromolecule, and/or biological organism of interest.

Methods for detecting analytes using conjugated polymers and the inner filter effect

The present invention provides novel polymer compounds and methods and processes for polymerizing and synthesizing the new polymers by post-modifying conjugated polymers bearing unsaturated functionalities. The post-modifications are facilitated by light-mediated initiators, thermal initiators, redox-based initiators, small molecule-based initiators, or a combination thereof. Syntheses and post-modifications are carried out to high conversion via thiol-ene 'click' chemistry-based mechanisms. The products comprise monomeric, oligomeric, and polymeric materials with easily-accessible pendant functionalities which impart new, distinct, and/or improved properties.

Thiol-based post-modification of conjugated polymers

The present invention provides novel methods and processes for polymerizing unsaturated substrates, such as alkyne bearing monomers, with arenes. The polymerizations are catalyzed by gold (Au) catalysts/complexes and/or other cocatalysts. The invention further provides novel structurally complex polymers prepared in high yield via an intermolecular polyhydroarylation mechanism. Such resulting products comprise oligomeric and polymeric materials with novel molecular architectures and microstructures, which subsequently impart unique properties. The invention includes both the synthesis methods and processes and the resulting compounds and compositions of matter.
