Solvation effects on spectral and photophysical properties of phenalenone dyes in polyurethane polymers

Ultrafast hybrid nanocomposite scintillators: A review

“…The development of filler injection techniques allows to significantly improve the properties of the resulting materials. There are on-going investigations of novel efficient PU-based scintillators doped with various organic phosphors [106], [111], [112], [113], [114] and rare-earth elements [107], [115]. The flexibility of chemical composition of the matrix allows to securely stabilize particles with high active surface area.…”

Photo-oxidation stability of microcapsules in thermochromic prints

“…Since the carbonyl groups are polar, formed hydrogen bonds are strong. As demonstrated by (Bezrodnyi, et al, 2016) the aliphatic polyurethane polymer matrix of high polarity has a potential ability to bond covalently with the -NH2 and -ОН substituent groups in the phenalenone dyes and a rigid fixation of the dye molecule with a polymer chain occurs. It causes higher photo-stability of dyes.…”
