    This article demonstrates the successful design and synthesis of a series of electrochromic polyureas capped with o-toluidine, PEG, ethoxysilane, and congo red end groups, respectively. The electrochromic properties, including color change, coloration efficiency, switching speed, and stability, have been effectively modulated.

    Aqueous self-assembly of diblock copolymers that have an alkoxysilane-functional group was studied. Two different synthesis methods, namely polymerization-induced self-assembly (PISA) and addition of a selective solvent, yielded greatly different results for the preparation of polymer nanostructures. Due to hydrolytic instability of the monomer in water, PISA proved unsuccessful. Preformed polymers in an organic solvent were successfully used to form self-assembled nanospheres via slow addition of water.

  3. Synthesis and thermal properties of linear polydicyclopentadiene via ring-opening metathesis polymerization with a third generation grubbs-type ruthenium-alkylidene complex

    Linear polydicyclopentadiene was produced with a third generation Grubbs-type Ru–alkylidene complex. At high catalyst loadings, the polymer shows a portion of the polymer with a low degree of branching owing to secondary ROCM as seen in the SEC analysis. Distinct signals are observed via low angle scattering analysis for polymers with twice or another multiple of the average molecular weight of the linear polymer hence strongly affecting the controlled-living nature of the polymerization.

  4. Double thermoresponsive block–random copolymers with adjustable phase transition temperatures: From block-like to gradient-like behavior

    In this work, an example for the design and synthesis of smart on-demand materials is presented. The discussed block copolymers show a precisely and easily adjustable temperature-induced micellization in water. Besides the micellization temperature, the mechanistic behavior of the system can be switched from block-like (unimers–micelles–clusters) to gradient-like (unimers–broad transition to clusters). With this, it offers appealing options to adapt its temperature response to the requirements of specific applications.

  5. Dithienosilole–phenylquinoxaline-based copolymers with A-D-A-D and A-D structures for polymer solar cells

    The strategy of using donor (D) and acceptor (A) conjugated copolymers with alternating electron rich and electron deficient units is effective in achieving high-performing solar cells. Two copolymers having D- A-D-A (P1) and D-A (P2) quinoxaline acceptor units and a dithienosilole donor unit were used as a donor along with PC71BM as an acceptor for polymer solar cells (PSCs). The optimized PSCs based on P1:PC71BM and P2:PC71BM active layers achieved power conversion efficiencies (PCE) of 7.16% and 6.57%, respectively. The PCE for P1 is attributed to higher crystallinity of P1 and good hole mobility, resulting in a more balanced charge transport.
