Stimuli-degradable polymers are regarded as interesting materials for various applications like patterning or drug delivery. In particular, light as a trigger received a lot of attention due to the possibility of adjusting wavelength, light intensity and irradiation time, which leads to a precise and controlled application. In this study, we report the synthesis of two novel light-degradable polyurethanes which are based on 6-nitropiperonal and differ in the implementation of the light-cleavable unit. Degradation of these backbone- or side-chain-cleavable polymers was analyzed by UV/Vis spectroscopy and SEC. While both polymers showed rapid decomposition in solution, differences in the degradation rates were observed dependent on the incorporation site of the light-cleavable unit. Furthermore, nanoparticles were fabricated and characterized by photon correlation spectroscopy as well as SEM proving the processability of the polymers for potential application as, e.g., a controlled release system.2-Aminopropane-1,3-diol(cas: 534-03-2Application of 534-03-2) was used in this study.
2-Aminopropane-1,3-diol(cas: 534-03-2) belongs to anime. Aniline, ethanolamines, and several other amines are major industrial commodities used in making rubber, dyes, pharmaceuticals, and synthetic resins and fibres and for a host of other applications. Most of the numerous methods for the preparation of amines may be broadly divided into two groups: (1) chemical reduction (replacement of oxygen with hydrogen atoms in the molecule) of members of several other classes of organic nitrogen compounds and (2) reactions of ammonia or amines with organic compounds.Application of 534-03-2
