My synthetic group designs and studies rigid molecular linkers  for the functionalization of semiconductor nanoparticles (TiO2 ZrOand ZnO) with dyes, chromophores and redox active groups.

 

 

 

 

 

 

 

The linker design is used  to control the distance, aggregation, binding and electronic properties of the dyes to the semiconductor surface.

 

Examples of linkers include tripods and rigid-rod molecules

 

The systems that we are  investigating range from simple molecules to complex supramolecular assemblies.

 

 The nanoparticle-linker-donor systems allow fundamental studies of dye-nanoparticle electronic interactions as well as more practical applications for photovoltaics (solar cells), sensors and other devices.

Representation of a  tripodal linker carrying a  Ru-polypyridyl complex and bound to the surface of a  TiO2 nanoparticle  through three COOH groups.

The TiO2 nanoparticles are typically ~20 nm in diameter. On each nanoparticle there are hundreds of dyes bound.

Photoexcitation of the chromophore (in this case the Ru complex) results in electron injection in the semiconductor.
