International Classification:

C07C24406

US Classification:

564308, 25230117, 25230121, 25230122, 252582, 252583, 252600, 430 72, 430 73, 544296

Abstract:

Disclosed are highly efficient multiphoton absorbing compounds and methods of their use. The compounds generally include a bridge of pi-conjugated bonds connecting electron donating groups or electron accepting groups. The bridge may be substituted with a variety of substituents as well. Solubility, lipophilicity, absorption maxima and other characteristics of the compounds may be tailored by changing the electron donating groups or electron accepting groups, the substituents attached to or the length of the pi-conjugated bridge. Numerous photophysical and photochemical methods are enabled by converting these compounds to electronically excited states upon simultaneous absorption of at least two photons of radiation. The compounds have large two-photon or higher-order absorptivities such that upon absorption, one or more Lewis acidic species, Lewis basic species, radical species or ionic species are formed.

Assignee:

International Classification:

G11C007/00

US Classification:

365/200000

Abstract:

A storage device for the storage and retrieval of arbitrary sequences of binary information provides areal densities exceeding terabytes per square centimeter (TB/cm) and even petabytes per square centimeter (PB/cm) in a 3D configuration. The information is encoded in long strands of biological or non-biological molecules such as artificial DNA, RNA or other synthetic molecules that form a macromolecule. The strands are written in-situ and, in some cases synthesized in-situ, transported to and from read and write stations and memory locations on the device. The data is read out by detecting individual bases or collection of bases directly from the strand.

International Classification:

G03H 112

US Classification:

430 1

Abstract:

The present invention comprises an optical data storage system utilizing a host material and molecules that exhibit non-linear absorption dissolved therein. The non-linear absorbing molecules allow for energy in the form of heat to be generated during the optical data storage process. This heat provides for localized alterations to occur in the pre-formatted holographic grating. The non-linear feature of these molecules allow for alterations to occur at specific depths and locations within the storage medium while limiting the secondary effects on other locations within the storage medium. The molecules exhibiting non-linear absorption may be selected from the group of molecules exhibiting two-photon absorption or reverse saturable absorption. The invention also comprises a method for preparing the optical storage medium, an optical data storage device comprising the optical data storage medium and having a format hologram stored within the medium. Additionally, the invention comprises an optical data storage system and method for use thereof wherein the storage system uses the optical data storage medium described above when altering a pre-formatted holographic grating in a localized region by non-linear thermal disruption of the grating.
