Paracyclophane Molecules for Two-Photon Absorption Applications
Tech ID: 10284 / UC Case 2004-244-0
Background
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.
Full 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.
Applications
• 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
