Abstract:
The morphology, optical, and molecular-conformation characteristics of amphiphilic molecular brushes with a polyimide main chain and poly(methacrylic)acid acid side chains loaded with the second-generation photosensitizer Radachlorine$^\circledR$ or a biogenic element (selenium in the zero-valence form Se$^0$) nanoparticles are studied using atomic force microscopy, UV spectroscopy, and dynamic/static light scattering. The effect of density $Z$ of grafts of poly(methacrylic)acid acid side chains and of the introduction of Radachlorine$^\circledR$ or Se$^0$ into amphiphilic molecular brushes on the size, spectral, and molecular conformation characteristics of synthesized binary nanosystems is demonstrated. A nonmonotonic dependence of the nanostructure size and the film surface roughness with increasing $Z$ in binary systems with Radachlorine$^\circledR$ and, conversely, a monotonic decrease in the nanostructure size and surface roughness for systems containing Se$^0$ nanoparticles are observed.
Keywords:
amphiphilic molecular brushes, photosensitizer Radachlorine$^\circledR$, selenium nanoparticles in zero-valence form, nanostructures, morphology, spectral and molecular conformational characteristics.
