We investigate several compounds of the type 1,1‘-(α,ω-alkanediyl)bis[pyrimidine] and 1-(ω-bromoalkyl)uracil, which can undergo photoinduced (2π + 2π) cycloaddition reactions on exposure to UV light at 254 and 257 nm, which have been synthesiz

Photodimerization of chromophores attached to a short peptide chain is investigated for high-capacity optical digital storage with UV lasers. The length and rigidity of the peptide chain assure an optimal distance and orientation of the chromophores

Ten Ne-glycylornithineamide derivatives have been synthesized containing various Nα-linked pyrimidine-1-ylacetyl groups which can undergo (2π + 2π) photodimerization on irradiation with UV light at 254 nm. The dimerization efficiency of the free a

The polyisoprene block of a polyisoprene-polydimethylsiloxane (PI-PDMS) diblock copolymer with 0.68 volume fraction of PI was tightly crosslinked with dicumylperoxide. The PDMS part of the obtained glassy material was subsequently quantitatively etch

The design, synthesis and optical holographic recording properties of bis-DNO are reported. Bis-DNO is composed of two identical azobenzene oligoornithine segments (DNO) connected via a dipeptide linker. The two segments were assembled in a parallel

A new family of proline-based azobenzene peptides (DNO) for holographic information storage is reported. By use of polarization holography, it was found that gratings with extraordinarily high diffraction efficiency (up to 80%) can be recorded in hun

Azobenzenes can serve as model compounds for the study of trans-cis isomerization in more complex molecules. We have performed time-resolved spectroscopy in solutions containing free azobenzene chromophores and diols with a view to obtaining the ener
