Eight novel polyurethanes with adjustable structures were prepared from two basic polymers; the compounds displayed good solubility in common organic solvents and high thermal stability. The presence of terminal alkyne moieties further improved the thermal stability of the polymers. The resonant d 33 values of the polymers could be improved up to 1.55 times by attaching suitable isolation...
The photophysical properties of fluorochromes are directly influenced by their chemical structure. There is increasing interest in chemical strategies that provide controlled changes to the emission properties of biologically compatible fluorophores. One strategy employed is the conversion of a fluorophore-attached alkyne to a triazole through a copper-catalyzed Sharpless-Meldal reaction. In this...
