Summary: The development of sustainable and degradable polymers like aliphatic polyesters has become increasingly important due to growing environmental concerns and depletion of fossil resources. gamma-Lactone-based polyesters have attracted attention for their ability to depolymerize. Functional monomers, such as sugar-based alpha-hydroxy-gamma-butyrolactone (HBL), can be used to tune the properties of these polyesters. In this study, random copolyesters of HBL and e-caprolactone (e-CL) were synthesized via ring-opening copolymerization using La[N(SiMe3)2]3 as a catalyst. High polymerization temperature (80 degrees C) was required for efficient monomer conversion. The characterization and kinetic investigations provided insights into the polymerization mechanism and the formation of different HBL monomer units (cyclic, linear, and branched). The use of La[N(SiMe3)2]3 catalyst achieved high HBL conversion ratio (over 85%) and enabled the synthesis of copolyesters with HBL units ranging from 9 to 63%.

Summary: ortho-Diethylhexyloxyphenylene benzothiadiazole paracyclophane-1,9-diene, a mixture of diastereomers, was synthesized through benzyne-induced Stevens rearrangement, oxidation, and pyrolysis. These cyclophanedienes, when reacted with Grubbs catalyst, can be opened to alternating cis,trans-phenylenevinylene polymers. In situ NMR experiments showed that one isomer polymerized to 90% conversion, while the other isomer gave only 9% conversion due to steric hindrance. The resulting polymers can be easily isomerized to all-trans isomer using visible light, and their optical and electrochemical properties were investigated by theory and experiment.

Summary: Researchers have developed a general strategy to generate chiroptical materials with multicolor and signinvertible circularly polarized luminescence (CPL) through charge-transfer (CT) complexation and co-assembly. The resulting assemblies exhibit intense CPL with highly tunable emission bands and handedness. Single-crystal analysis shows that the molecular packing is alternately and asymmetrically arranged through CT interactions, leading to efficient transfer and inversion of chirality.

Summary: We present the first structures of an unusual helix formed by a heteromeric sequence of alpha- and delta-amino acids and demonstrate its application in catalysis. The helix formation is driven by intramolecular hydrogen bonds, but we also observed an apolar interaction that stabilizes one type of helix over another. This unique stabilization enables the alpha-residues to engage in bifunctional catalysis.

Summary: We describe a facile method to produce circularly polarized luminescence (CPL) from helicene racemates via supramolecular association with DNA in aqueous solution. Racemic cationic helicene derivatives are immobilized in the grooves of commercially available double-stranded right-handed DNA, and the discrimination of left- and right-handed helicenes by chiral DNA is monitored by single molecule force spectroscopy. This strategy provides a distinctive insight into the fabrication of CPL-emitting systems.

Summary: This study reports a rigid and dinucleophilic cage (PNSiMe3)2(NMe)6 that acts as a linear and divalent connector to form cage-dense inorganic materials. The cage reacts with different ditopic P(III) dihalide comonomers to produce high molecular weight, solution-processable polymers that form free-standing films. By tuning the end groups of the polymers, block copolymers can be formed. Networked cage-dense materials can be accessed using PCl3 as a tritopic P(III) linker. The study provides a general strategy for making cage-dense polymers and offers insight into the influence of three-dimensional microstructures on macroscopic material properties.

Summary: Remote C-H functionalization is an important process for the conversion and utilization of arenes. A metal/template-free electrochemical strategy is developed for remote C-H functionalization in a helical system, where hydrogen atoms act as directing groups to facilitate alkoxylation. This strategy allows precise decoration of inert helicene skeletons with various alkoxy pendants. Selective decoration of a methoxy group on N-methylated aza[6]helicene leads to distinct luminescence variation upon changing solvents.
