A series of molecular brushes with a polyfluorene (PF) backbone and polymethacrylic acid side chains of varying lengths were prepared by atom transfer radical polymerization. The structure and composition of the synthesized compounds were confirmed by ¹ H NMR and IR spectroscopy. Effect of the length of the backbone on spectral and conformational p...
The functionalization of copolyfluorenes containing dicyanophenanthrene units by closo-decaborate anion is described. Target copolyfluorenes were analyzed using SEM, UV-vis, luminescence, NMR, and Fourier-transform infrared (FTIR) spectroscopy. The effect of complexation with the closo-decaborate anion on the photophysical properties was studied bo...

Using palladium-catalyzed Suzuki polycondensation, we synthesized new light-emitting fluorene copolymers containing the dicyano derivatives of stilbene and phenanthrene and characterized them by gel permeation chromatography, UV-vis absorption spectroscopy, spectrofluorimetry, and cyclic voltammetry. The photoluminescence spectra of the synthesized...
Graft copolymers with the polyfluorene backbone and poly(tert-butyl methacrylate) and poly(methacrylic acid) side chains are synthesized by atom transfer radical polymerization. The behavior of the synthesized brushes in chloroform, ethanol, and water solutions is studied by molecular hydrodynamics and optics. The graft copolymers are characterized...

Novel polyfluorene polymer brushes with polymethacrylic acid side chains were obtained by atom transfer radical polymerization (ATRP) and activator generated by electron transfer (AGET) ATRP of tert-butyl methacrylate on polyfluorene multifunctional macroinitiator, followed by protonolysis of the tert-butyl groups of the side chains. Kinetics of po...
A series of 3(2)-phosphonylated thiazolo[3,2- a ]oxopyrimidines was synthesized for the first time by the reactions of chloroethynylphosphonates with unsubstituted and 5(6)-substituted 2-thiouracils. The reaction of chloroethynylphosphonates with 6-substituted 2-thiouracils bearing electron-donor groups (CH 3 , Ph) proceeded with high regioselectiv...
A series of novel 2-phosphonylated imidazo[1,2-a]pyridines was accessed from C–N coupling of chloroethynylphosphonates and commercially available N-unsubstituted 2-aminopyridines. The product yield depends on the nature and position of the substituent in the pyridine ring.
