Three-Dimensional Optical Recording in tert-Butoxycarbonyl-Protected Quinizarin Methacrylate Polymers

چکیده
We report photoacid-induced nonerasable recording in tert-butoxycarbonyl-protected quinizarin methacrylate polymers for three-dimensional optical memory. 1m/s-speed recording was achieved using an 800 nm femtosecond laser at an 80MHzrepetition rate, without a postexposure bake after laser irradiation. Three-layer recording indicates that no optical damage during recording enables modulation of the Compact Disc type memory. The linewidth of recorded marks of 0.4 mm indicates a 49Gbits/cm areal density when the numerical aperture is 1.35. [DOI: 10.1143/JJAP.45.1640]

The synthesis of the (2S)-[3-(anthracen-9-yl)-4,5-dihydroisoxazol-5-yl]methyl 2-[(tert-butoxycarbonyl)amino]propanoate is obtained through the 1,3-dipolar cycloaddition of the stable anthracenenitrile oxide and the N-Boc protected (S)-alanine allyl ester as dipolarophile. The structure and the fluorescence properties are described upon the relative analytical and spectroscopic data.
متن کاملPreparation of the 4-hydroxytryptamine scaffold via palladium-catalyzed cyclization: a practical and versatile synthesis of psilocin.
[reaction: see text] The 4-hydroxytryptamine scaffold of psilocin was successfully prepared via palladium-catalyzed cyclization of protected N-tert-butoxycarbonyl-2-iodo-3-methoxyaniline and an appropriately substituted silyl acetylene. Removal of the protecting groups afforded psilocin in good yield.
متن کاملDoxorubicin degradation in cardiomyocytes.
Antitumor therapy with the anthracycline doxorubicin is limited by a severe cardiotoxicity, which seems to correlate with the cardiac levels of doxorubicin and its metabolization to reactive oxygen species. Previous biochemical studies showed that hydrogen peroxide-activated myoglobin caused an oxidative degradation of doxorubicin; however, a pharmacological evaluation of this metabolic pathway...
متن کاملOptical pH Sensor Based on Quinizarin for Alkaline pH Regions
The development of an optical pH sensor based on immobilization of quinizarin (1,4-dihydroxyanthraquinone) on a triacetylcellulose membrane was described. The resulting membrane exhibited fast color change from yellow to violet, while changing the pH in alkaline region. The immobilized quinizarin showed a broader dynamic range from (pH 9.4-11.4) with respect to free form (pH 8.8-10.4). The sens...

Antigen uptake by dendritic cells (DCs) is a key step for initiating antigen-specific T cell immunity. In the present study, novel synthetic polymeric nanoparticles were prepared as antigen delivery vehicles to improve the antigen uptake by DCs. Well-defined cationic and acid-responsive copolymers, monomethoxy poly(ethylene glycol)-block-poly(2-(diisopropyl amino) ethyl methacrylate)-block-poly...
