“…This example concerns the linear semiconducting BCP poly[2,7-(9,9-dihexylfluorene)]-b-poly (2,2,3,3,4,4,4-heptafluorobutyl methacrylate (PF-b-PHFBMA). 38 A series with varying PHFBMA block lengths (Table 1, entries 5-9) was synthesized by atom transfer radical polymerization (ATRP) using a 2-bromoisobutyryl-endcapped polyfluorene (PF-Br) as a macroinitiator for polymerization of heptafluorobutyl methacrylate. In contrast to the previous example, the retention time does decrease when converting the PF homopolymer into the BCP (compare Table 1 entries 5 and 6, and the SEC traces in Fig.…”

“…For example, stiff, rod-like conjugated polymers (e.g., poly(3-hexylthiophene)) have different elution behavior relative to coiled flexible polymers like polystyrene, which is a typical SEC standard. 21 Junkers et al 22 have documented cases of anomalous SEC elution of block copolymers arising from not only rod-coil morphologies, 23 but also different block solubilities in the mobile phase (e.g., polyfluorinated side chains), 24 selfassembly via hydrogen-bonding, 25 and interactions with the stationary phase. 26 PBN2VN is chemically similar to polystyrene with respect to a flexible backbone and similar solubility properties, suggesting that SEC relative to PS standards should be a reasonable method for S1 for complete data set molecular weight characterization.…”

The synthesis of vinyl alcohol copolymers is limited due to the poor radical reactivity of vinyl acetate (VAc), the traditional precursor to polyvinyl alcohol (PVA). Main group monomers such as BN 2‐vinylnaphthalene (BN2VN) have attracted attention as alternatives to VAc to form side chain hydroxyls via oxidation, but outstanding questions of molecular weight control remain. Herein we report systematic investigation of solvent, temperature, and initiator concentration as factors influencing BN2VN degree of polymerization. We find increased chain transfer to toluene, hypothesized to arise from differences in radical stabilization and reactivity by aromatic and BN aromatic rings. As a result of these combined efforts, high molecular weight (Mw ~ 105 g mol−1) BN2VN homopolymers and BN2VN‐styrene copolymers were obtained.

“…The chemical shifts seen for the protons of the carbon atoms 5 and 6 are due to the inductive effect of the oxygen atom, strongly electronegative element. Hydrogen atoms of the aromatic chain absorb energy in a magnetic downfield with signs in the region between 7.88 and 8.87 ppm [26,28,[30][31][32].…”

This work reports the synthesis and characterization of a conjugated polymer based on fluorene and terpyridine, namely, poly[(9,9-bis(3-((S)-2-methylbutylpropanoate))fluorene-alt-6,6′-(2,2′:6′,2′′-terpyridin-6-yl)] (LaPPS71). The structure was characterized by 1H and 13C nuclear magnetic resonance (NMR) and Fourier-transform infrared (FTIR) spectroscopy. The molar mass was measured by gel permeation chromatography (GPC). As thermal characterization, the glass transition temperature (Tg) was measured by differential scanning calorimetry (DSC). The polymer structure contains two sites capable of complexation with metallic ions, affording the possibility of obtainment of independent or electronically coupled properties, depending on the complexation site. The photophysical properties were fully explored in solution and solid state, presenting ideal results for the preparation of various metallopolymers, in addition to potential application as a metamaterial, due to the presence of the chiral center in the side chains of the polymer.
