This review provides an overview of the history of preparing representative photovoltaic polymers utilized in polymer solar cells through direct arylation reactions and discusses the activity and selectivity of C−H bonds in typical building blocks under different reaction conditions.

Chlorinated Perylene-3,4-(dicarboxylic monoimide)-9,10-(dicarboxylic monoanhydrate) (PIA) could be synthesized via a simple hydrolysis reaction using LiOH as the base, then a perylene diimides dimer connected at the imide position, N-di-PDI-4Cl, is synthesized via one-step condensation reaction as an application example of chlorinated PIA.

The SN-based electrolyte with low-flammability has been successfully through in-situ polymerization method. The as-prepared SN-based electrolyte exhibited good electrochemical performance and low-flammability.

Four Al-based complexes with different sidearms were prepared and applied for controlled polymerization of pentadecalactone (PDL) furnishing polyesters with M_w high up to 90.3 kg/mol. Well-defined block copolyesters and random copolyesters with tailored T_m has also been obtained by copolymerizing PDL with small-lactones with controlling the polymerization condition.

The poly[(vinyl chloride)-co-(n-butyl acrylate)-co-(vinyl acetate)] random terpolymers are synthesized successfully via precipitation polymerization. The reaction medium and the monomer feed ratios are crucial factors both for the polymer morphology and reaction kinetic. Moreover, precipitation polymerization is suitable to synthesize ternary copolymer with low number-average molecular weight and high content of BA.

We first utilized the solubility of dimethylglyoxime in polyethylene glycol to prepare a recyclable and self-healing crosslinked polyurethane through bulk polymerization. By introducing metal coordination, we can enhance its strength and promote dynamic reversibility. The key to these improvements lies in the coordination and catalytic effect of copper ions.

DGEMP was synthesized via substitution and epoxidation from magnolol, which was used as a reactive additive for traditional DGEBA epoxy resins. DGEBA/DGEMP showed excellent mechanical and flame retardant performance.

The prodrug strategy significantly increased the encapsulation efficiency and cancer cell selectivity of paclitaxel. The iodination endows the nanoparticles with CT-imaging capacity. The GSH-responsiveness of polymer further facilitates the intracellular drug release. Therefore, efficient antitumor therapy and real-time monitoring of the therapeutic efficacy might be simultaneously achieved.

A series of benzocyclobutene (BCB)-based polymeric low-dielectric (low-k) materials were synthesized based on a novel linear fluorinated BCB-type monomer (4F-bis-BCB) with simple and efficient one-step preparation method, exhibiting excellent low dielectric and tunable mechanical properties, as well as great potential for next-generation advanced packaging applications.

Hyperbranched polymeric fluorosurfactants had a strong synergism with the small molecule fluorosurfactant C1157 in raising their surface activity, which favored their use for highly efficient fire-extinguishing towards flammable oils.

1D flexible coaxial piezoelectric fiber (1D-PFs) is fabricated by a one-step but continuous way, whose electrode can be protected by piezoelectric layer. It can be further endowed with 3D helical structure to realize excellent stretchability. Moreover, wearable and washable motion monitoring system can be constructed based on such 3D helical fiber.

The light curing system is designed based on crosslinking reaction and in-situ chain extension which can be applied in 3D printing, resulting in lower viscosity of the precursor before printing and considerable mechanical properties after printing.

Novel supramolecular silicone poly(urea-urethane) (SSPu) coatings with excellent mechanical performance, strong interfacial adhesion and multiple time recycling capability are developed by incorporating noncovalent bonds (2-amino-4-hydroxy-6-methylpyrimidine (UPy) quadruple hydrogen bonds) into the side chain of silicone backbone.

In this work, fully biodegradable PGA/PBSA films with high PGA content were developed by extrusion blown film technique. The hierarchical structure of PBSA nanofibers and interfacially oriented PGA crystals enable the films to have high barrier performance and mechanical properties.

A new modified species of butyl rubber (IIR), epoxidized butyl rubber (EIIR) was synthesized by in situ epoxidation technique for the first time. The epoxidation degree of EIIR reached about 99 %. The EIIR/CB composite crosslinked by maleic anhydride had excellent mechanical properties, and the airtightness and fatigue life were substantially improved compared with those of IIR.
