Summary: Incorporation of heteroatoms into polyarenes has been proven to be an effective method to modify their structures and properties. In this study, P=O-containing dibenzopentaarene isomers (5a and 5b) were designed and synthesized, and their structures and properties were investigated alongside dibenzopentaarenes containing Si and B heterocycles (3 and 4). The incorporation of heterocycles greatly influenced the molecular and packing structures, as well as the electronic structures and properties of the polyarenes.

Summary: In this study, a series of poly(arylene ether sulfone) (PAE) copolymers with pendant alkenes were synthesized using benzenesulfonamides as comonomers, and the thermal properties of the resulting polymers were found to be dependent on the choice of sulfonamide regioisomer. Ortho/meta and meta/meta benzenesulfonamides were insensitive to thiol-ene modification, while other substitution patterns showed significant variations in properties based on the functional group installed.

Summary: Two series of random copolymers with carbazole and coumarin fluorescent groups linked to a poly(norbornene dicarboximide) backbone were prepared by controlled ring-opening metathesis polymerization. The study showed differences in fluorescence behavior in solution and solid state due to energy transfer phenomena between the two fluorescent groups, revealing the mechanism of energy transfer between carbazole and coumarin moieties.

Summary: In this study, ladder-like polysiloxanes with high triplet energy were synthesized by introducing double-chain Si-O-Si polymer as the backbone and carbazole and triphenylphosphine oxide as side groups. The ladder-like structures were achieved through controlled polymerization method. The introduction of siloxane improved thermal stability and increased triplet energy level. The measurements showed that the bipolar polymer exhibited high HOMO value and facilitated hole and electron injection.

Summary: Metal halide perovskite shows great potential for applications in various optoelectronic devices due to its excellent optoelectronic properties, low-cost raw materials, and easy fabrication process. However, the presence of defects, ion migration, and limited stability in polycrystalline thin-films hinder their device performance. In contrast, perovskite single crystals demonstrate better properties and stability, making them an attractive choice for optoelectronic devices and fundamental research. This review summarizes recent progress in the growth methods of perovskite single crystals, discusses their intrinsic properties, and explores their applications in different optoelectronic devices.

Summary: We synthesized a series of block copolymers with nonconjugated pendant electroactive polymer (PCzETPMA) and polystyrene (PS) block through an anionic living polymerization. By controlling the molar masses, PS to PCzETPMA block ratios, and tacticities of the PCzETPMA blocks, we were able to increase the hole mobilities of the resulting copolymers. The highest hole mobility achieved was 2.33 x 10(-5) cm(2)/V center dot s for the copolymer with the highest molar mass and dominant isotactic PCzETPMA block.
