Latest Patents
Engbersen's latest patents involve the development of optically non-linear active waveguiding materials that comprise an optically transparent polymer combined with specific dopants. His first patent describes a material incorporating a donor group and an acceptor group-containing triphenylcarbinol as a dopant. This invention emphasizes the dopants' high hyperpolarizability and their ability to possess a charge-transfer absorption band similar to compounds with a single donor-π-acceptor unit. It highlights preferred nitro-functionalized triphenylcarbinols due to their advantageous charge-transfer absorption bands at low wavelengths.
In his second patent, Engbersen explores a similar concept but with dopants containing more than one donor-π-acceptor unit. The patent outlines the suitability of cyclic groups of these dopants, particularly calix(4)arenes, for their excellent hyperpolarizability and their solubility in host polymers like polymethylene (meth) acrylate and polystyrene. These structures are positioned as promising candidates for frequency doubling applications, expanding the potential uses of optically non-linear materials.
