Photoresponsive Covalently-Functionalized Short Single Wall Carbon Nanotubes

In-plane elastic moduli of covalently functionalized single-wall carbon nanotubes

Optically modulated conduction in chromophore-functionalized single-wall carbon nanotubes.

We demonstrate an optically active nanotube-hybrid material by functionalizing single-wall nanotubes with an azo-based chromophore. Upon UV illumination, the conjugated chromophore undergoes a cis-trans isomerization leading to a charge redistribution near the nanotube. This charge redistribution changes the local electrostatic environment, shifting the threshold voltage and increasing the cond...

Self-assembled lamellar structures with functionalized single wall carbon nanotubes.

Highly ordered self-assembled multi-layer structures with denatured collagen wrapped single wall carbon nanotubes and surfactant systems were obtained through bioinspired methodology.

Rectifying diodes from asymmetrically functionalized single-wall carbon nanotubes.

Asymmetrically functionalized single-wall carbon nanotubes (SWNTs) have been prepared by a covalent reaction of an 11-mercaptoundecanol-modified Au surface with oxidized SWNT cylinders. While one end of the tubes is attached to gold substrate via ester groups, the free carboxylic substituents on the other end can be either ionized (CO2-) or esterified (CO2Et), creating a donor-acceptor asymmetr...
