Strongly UV Absorbing Bifunctional Azoalkanes

Organic Letters, 2001
[structure: see text] Two new anthracene-containing azoalkanes (1 and 2) absorb UV light 600 times more strongly than simple azoalkanes. Intramolecular energy transfer from excited singlet anthracene to the azo group is nearly complete, but despite the close proximity of the two chromophores, 1 and 2 continue to exhibit anthracene fluorescence ...

Inorganic UV absorbers for the photostabilisation of wood-clearcoating systems: Comparison with organic UV absorbers

Applied Surface Science, 2007
Inorganic UV absorbers which are widely used today were originally designed neither as a UV blocker in coatings applications, nor for wood protection. In recent years however, there has been extensive interest in these compounds, especially with regard to their properties as a UV blocker in coating applications.

Copolymerization of UV-absorbers, II

Die Angewandte Makromolekulare Chemie, 1998
Polymerizable UV-absorbers, such as 4-allyloxy-2-hydroxy-4'-methylbenzophenone and 4-allyloxy-2-hydroxy-4-methoxybenzophenone were copolymerized with styrene to give copolymers containing 2-8% of UV-stabilizer. The copolymer films were subjected to UV-irradiation, and the carbonyl index, hydroxy index, tensile strength, elongation at break and ...

Triplet–Triplet Energy Transfer from a UV‐A Absorber Butylmethoxydibenzoylmethane to UV‐B Absorbers

Photochemistry and Photobiology, 2014
AbstractThe phosphorescence decay of a UV‐A absorber, 4‐tert‐butyl‐4′‐methoxydibenzolymethane (BMDBM) has been observed following a 355 nm laser excitation in the absence and presence of UV‐B absorbers, 2‐ethylhexyl 4‐methoxycinnamate (octyl methoxycinnamate, OMC) and octocrylene (OCR) in ethanol at 77 K. The lifetime of the lowest excited triplet (T1)
