posted on 04/29/2009

Organic molecules that absorb two or more photons simultaneously have wide applications in a variety of technologies involving such subjects as optical data storage, 3-D microfabrication techniques, frequency upconverting lasing, optical power limiting, photodynamic therapy, initiators of polymerization reactions, and multi-photon fluorescence microscopy for biological imaging.

Suggested Uses

• Photo-polymerization initiators and two-photon fluorophores

• Biological imaging

• Optical data storage

This technology is available for licensing.

Advantages

• Produces free radicals that initiate polymerization process

• Three dimensional spatial resolution

• Absence of single-photon absorption

• Allows an incident light beam to penetrate deeper into a material

Innovation Details

Detailed Description

In one aspect, the present invention is directed to two-photon or other multi-photon absorbing chromophores having a conjugated pi-electron system, with donating groups at each end of the pi-electron system providing charge-transfer properties. The present invention also provides photo-polymerization compositions and a method of photo-polymerization, each incorporating chromophores of the present invention.
