Summary: This study investigates the role of three conjugated microporous polymer materials in the separation of xenon and krypton. The results show that the CMP-PY-TBTP polymer exhibits the highest selectivity for xenon/krypton separation, while the CMP-PY-TFB polymer exhibits the highest xenon adsorption. These findings have important applications in the separation of xenon and krypton in nuclear waste reprocessing.

Summary: Four novel isoindigo-thiophene D-A-D-type precursors were synthesized and electrosynthesized into corresponding hybrid polymers with favorable electrochemical and electrochromic performances. The resultant polymer combines the merits of isoindigo and polythiophene, and exhibits high stability and extraordinary electrochromic stability. The isoindigo-thiophene D-A-D-type polymers also possess high optical contrast, fast switching time, and high coloration efficiency, making them potential candidates for electrochromic materials.

Summary: Conjugated polymers play a crucial role in flexible bioelectronics due to their organic nature that allows for modification and tuning. The use of dopants in organic semiconductors can result in deterioration of electronic properties, leading to the development of self-doped and self-acid-doped polymers. While the terms are often used interchangeably, their doping mechanisms differ, with self-doped polymers requiring an external dopant for charge transfer and self-acid-doped polymers being inherently doped. Drawing a distinction between the two categories is important to understand their unique properties and potential applications. Examples of self-acid-doping in bioelectronics highlight the stability of these polymers under physiological conditions. However, a lack of clarity in terminology in the literature limits the understanding and development of these important bioelectronic components.

Summary: Direct (hetero)arylation polymerization (DHAP) is a promising method for the preparation of conjugated polymers that is simple, low cost, and environmentally friendly. However, the selectivity of the coupling reaction has always been a challenge. This study investigated the conditions for C-C couplings between 2-methylthiophene and 2-thiophenecarbonitrile, with one of the partners brominated, and found that the best conditions are achieved when the electron withdrawing moiety is halogenated.

Summary: We reported the charge-transfer-driven self-assembly of conjugated block copolymers into highly doped conjugated polymer nanofibers. The presence of polyethylene oxide (PEO) block played an important role in stabilizing nanoscale charge transfer assemblies. The doped nanofibers exhibited efficient photothermal properties in response to various external stimuli.

Summary: This paper investigates the electronic structure and photophysical properties of two diblock & pi;-conjugated oligomers. The experimental results are supported by density functional theory calculations and time-dependent DFT calculations. The fluorescence and transient absorption spectroscopy results show that the photophysical properties and dynamics of the excited states are similar for T4-TBT and T8-TBT.

Summary: This paper investigates the electronic structure and photophysical properties of two diblock π-conjugated oligomers with electron rich tetra(thiophene) (T4) or octa(thiophene) (T8) segments linked to an electron poor 4,7-bis(2-thienyl)-2,1,3-benzothiadiazole (TBT) moiety. The results show that the diblock oligomers display redox and absorption features that can be attributed to the Tn and TBT units, and the frontier orbitals on the diblock oligomers retain characteristics of the individual π-conjugated segments. Moreover, the fluorescence and transient absorption spectroscopy reveal that the photophysical properties and dynamics of the excited states are dominated by charge transfer between the oligo-thiophene and TBT units.

Summary: Quick and sensitive virus detection methods have been developed using sub-picoliter microwells. The methods include the use of an aggregation-induced emission (AIE) reagent and enzymatic reaction supported with high-concentration immunomagnetic beads. The AIE reagent method achieved a detection limit of 3 x 10^5 copies/mL within 1 minute, while the high-concentration immunomagnetic beads method had a detection limit as low as 1 x 10^2 copies/mL.
