  • METALLIC SINGLE-WALLED CARBON NANOTUBE HYBRID ASSEMBLIES AND SUPERSTRUCTURES
    Publication number: 20250019243
    Abstract: A metallic single-walled carbon nanotube (SWNT) hybrid assembly or superstructure includes a single walled carbon nanotube (SWNT) having a chiral index (n, m) where (n?m)/3 is an integer or 0; and an oligomer or polymer that single-chain wraps the metallic SWNT, wherein the oligomer or polymer is formed of repeat units, wherein each repeat unit has at least one charged functional group per 1-3 nm of oligomer or polymer length. The superstructure is suitable for optical, electro-optical, and spintronic-based device applications.

  • Iron chromophores for energy conversion
    Patent number: 12074000
    Abstract: Iron-based photosensitizers, which can be used for solar energy conversion and photoluminescence applications, include an iron complex with N-heterocyclic carbene (NHC) ligands (FeNHC), a linking unit, and a polarizable unit formed of a pi conjugated structure having a one-electron reduction potential more positive than NHC.

  • Control of trion density in carbon nanotubes for electro-optical and opto-electric devices
    Patent number: 11508462
    Abstract: An optoelectronic system can include a single walled carbon nanotube (SWNT) device. The SWNT can include a carrier-doping density with optical conditions that control trion formation that respond via optical, electrical, or magnetic stimuli. The carrier-doping density can include a hole-polaron or electron-polaron concentration.
