	Abstract:Poly(3-methacrylamido phenylboronic acid) (PMAPBA) homopolymer and poly(ethylene glycol)-b-poly(2-acryloxyethyl-galactose) (PEG-b-PAEG) glycopolymer were prepared successfully by reversible addition fragmentation chain transfer polymerization (RAFT) and atom transfer radical polymerization (ATRP), respectively. The formation of boronate crosslinked micelles based on the complexation of PMAPBA and PEG-b-PAEG were confirmed by dynamic light scattering (DLS), thermal analysis, and Alizarin red S (ARS) based colorimetric and fluorescence assay. The micelles showed significant pH, salt, and glucose sensitivity. At pH 5.0 and 6.0, the aggregation and precipitation of the micelles was observed. The particle size increased significantly as pH increased from 7 to 11. Due to shielding of the negatively charged phenylboronic acid groups, the aggregation of the boronate crosslinked micelles were found with increase of the salt concentration. Additionally, the glucose-responsive behavior of the micelles was dependent on the pH value. The sensitivity of the micelles to glucose was stronger at higher pH values.

	Abstract:Three novel soluble alternating conjugated copolymers PT-TZN, PF-TZN, and PBDT-TZN, comprised of thiophene, fluorene, benzo[1,2-b:4,5-b']dithiophene and thiophene derivatives with 3-nitro-1,2,4-triazole side chains, were synthesized via the palladium-catalyzed Suzuki coupling reaction and Stille coupling reaction. The effects of 3-nitro-1,2,4-triazole on the thermal, photophysical, electrochemical and photovoltaic properties were investigated. The introduction of the 3-nitro-1,2,4- triazole side chains benefits to lowering the bandgaps of the polymers. The bulk-heterojunction polymer solar cells were fabricated based on the blend of the as-synthesized polymers and the fullerene acceptor [6, 6]-phenyl-C61-butyric acid methyl ester (PCBM). The maximum power conversion efficiency (PCE = 1.13%) was obtained with PBDT-TZN as the electron donor under the illumination of AM 1.5, 100 mW cm-2. The study results indicate that low bandgap derived from too strong electron-withdrawing groups does not always benefit to the PCEs of PSCs.
