摘要:
The present invention relates to new coumarin compounds and to their use as dyes in optical layers for optical data recording, preferably for optical data recording using a laser with a wavelength up to 450 nm. The invention further relates to an optical layer comprising said dyes and to a write only read many (WORM) type optical recording medium capable of recording and reproducing information with radiation of blue laser, which employs a coumarin type dye in the optical layer.
摘要:
Photo-active devices including a substrate, a first electrode, an active layer including an organic salt or salt mixture that selectively or predominantly harvests light from the near infrared or infrared regions of the solar spectrum, and a second electrode. The devices are either visibly transparent or visibly opaque and can be utilized in single- or multi-junction devices.

bei der die verwendeten Symbole die in der Beschreibung angegebene Bedeutung haben, ein Verfahren zu deren Herstellung und deren Verwendung in thermischen und fotochromen Aufzeichnungsmaterialien, als nicht lineare optische Materialien, als Fotoleiter in der Elektrofotografie und zum Färben von Fasern und Geweben von Polyester und von Kunststoffen.
摘要:
This invention relates to an optical recording medium, comprising a substrate, a reflecting layer and a recording layer based on compounds of formula (I), (II), (III) or (IV). Attention is drawn to the description for the precise meanings of the substituents. Recording and playback are carried out especially at a wavelength of from 350 to 500 nm, for example using a blue laser. The recording and playback quality is excellent and allows high storage density. Likewise claimed are some novel compounds of formula (I), (II), (III) or (IV), as well as an optical recording medium comprising, in the following arrangement, a) a supporting material consisting of a reflecting metal or, preferably, of a polymer having a reflection metallic layer; b) an optical recording layer; c) a separating layer consisting of a metallic, crosslinked organometallic or dielectric inorganic substance; and c) a covering layer.

The present invention provides methods, compositions, mixtures and kits utilizing deoxynucleoside triphosphates comprising a 3′-O position capped by a group comprising methylenedisulfide as a cleavable protecting group and a detectable label reversibly connected to the nucleobase of said deoxynucleoside. Such compounds provide new possibilities for future sequencing technologies, including but not limited to Sequencing by Synthesis.
