“…30 Branched polymers with useful rheological and mechanical properties, such as star-shaped polymers, hyperbranched polymers and dendrimers, have attracted a great deal of attention by research groups all over the world. [31][32][33] With several branches extending from a single point, 34 star-shaped polymers applied in drug carriers have advantages such as a lower solution viscosity, a smaller hydrodynamic radius, a higher encapsulation efficiency and loading content compared with linear polymers in a drug delivery system. 32,[35][36][37] Therefore, star-shaped block copolymers based on PCL, PLA, PEG 1k and CA could potentially be used to prepare excellent biodegradable drug-carriers.…”

“…The second step was polymerization reaction, where (9-carbazolyl)-methytiirane reacted with oligo(potassium glycidoxide) synthesized in the reaction of glycidol with potassium hydride in the presence of 18-crown-6 in tetrahydrofuran ( Scheme 1 ). The formation of the compound and its luminescent properties are described in detail in the papers [ 24 , 25 , 26 ].…”

This article presents the results of research related to the development of cellulose man-made fibers with luminescent properties. The fibers were obtained from regenerated cellulose with the use of the N-Methylmorpholine-N-Oxide (NMMO) method for lyocell (Tencel) fiber formation. The method is named after the cellulose solvent (NMMO) used to obtain the spinning solution. Fibers are formed by the dry–wet spinning method. Due to the characteristic of the lyocell process, the fibers were easily modified to achieve luminescent properties with star-shaped organic compound poly((9-carbazolyl)methylthiirane) (KMT). Fibers were examined on their mechanical parameters with the use of Zwick Z2.5/TN1S tensile testing machine, and the results show the influence of the KMT concentration in the fiber matrix on mechanical parameters of the fibers. The study also attempted to determine the concentration of the modifier in the fibers with the use of UV-VIS Spectrofluorometer JASCO. The luminescent properties of fibers were estimated as well, using Jobin–Yvon spectrofluorometer FLUOROMAX–4, and the results are very promising as the fibers emit blue light in the range of visible light spectrum even for small concentrations of KMT (about 0.1 wt.%).

“…These macromolecules are widely used in various fields of nanotechnology, for example as a template for the synthesis of nanoparticles [15] or as emitting devices [16][17][18]. Charged macromolecules easily interact through electrostatic forces with negatively charged DNA, forming stable complexes for further transporting it into a living cell.…”

The entropic sampling Monte Carlo method within Wang-Landau algorithm is applied to investigate properties of a lattice model of strongly charged flexible 3-arm star-shaped polyelectrolyte. The density of states is calculated, from which the canonical properties of the system in a wide temperature range are obtained by simple integration. The effects of the arm length and the short-range monomer-monomer potential on the thermal and structural properties of star polyions are studied. We calculate such characteristics as mean square radius of gyration and its components, the radius vector of the center of mass, components of the tensor of inertia and parameters characterizing the shape of the polyion. In this work, we focus on how these characteristics are influenced by the change of the reduced temperature which, within the considered model, is a parameter combining the effect of real temperature, linear charge density and solvent dielectric permittivity. The coil-globule transition is observed in most of the considered cases, and for the polyions with the longest length of arms (24), the transition from a liquid globule to a solid-like state is observed. Comparison of polyelectrolyte models with neutral ones is given.
