Recent progress of heterocycle ring‐opening (co)polymerization for the synthesis of sequence‐controlled block polyesters and polycarbonates

Smart Molecules, EarlyView.
Block copolymers are fundamental for the development of smart molecules. Aliphatic polyesters and polycarbonates have received attention as heteroatom‐containing polymers that are biodegradable and biocompatible. Block polymers from polyesters and polycarbonates have the ability to form smart molecules. This review presents the heterocycle monomer ring‐

From Molecular Bricks to Sustainable Nanomaterials: An Accurate and Scalable Unsupervised Workflow

Small Structures, EarlyView.
An adaptive accuracy framework integrates Pisa Composite Schemes with the Nano‐LEGO platform for data‐driven molecular design. Molecular fragments validated through explicitly correlated and bond‐corrected DFT models enable scalable prediction of structural and spectroscopic properties.

Heterobimetallic Pt(II) Complexes Supported by 1,8‐Naphthyridine Ligands Confirm the Rotation of C6F5 Groups about the Pt−C Bond

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
You Spin Me Round. The ligand 1,8‐naphthyridine is able to stabilize heterobimetallic complexes containing Pt(II)→M (M = Ag, Cu) donor–acceptor bonds, in which the rotation of the C6F5 ligands in solution can be stopped at low temperature. The ligand 1,8‐naphthyridine (napy) exhibits a rich coordination chemistry arising from the disposition of its two

Exploration of questionable backbone conformations in crystallographic structure models using a structural alphabet

Acta Crystallographica Section D, EarlyView.
We present a protocol to detect and characterize questionable backbone conformations in X‐ray protein structure models. These conformations may arise from artifacts related to the crystallization process or from errors introduced during model building and refinement.

Major Cat Allergen Fel d 4: Structure and Identification of a Cross‐Reactive IgE‐Epitope‐Containing Area

Allergy, EarlyView.
This study reports the three‐dimensional structure of an important cat allergen, Fel d 4, that shares high homology with Equ c 1 (i.e., major horse allergen) and Can f 6 (i.e., dog allergen). The C‐terminal region of the Fel d 4 contains a major IgE‐reactive epitope.
