Acetoacetates Derived From Vegetable Oils: A Platform for Tailor‐Made Vinylogous Urethane Foams
A renewable vegetable oil is converted into acetoacetate‐functionalized precursors for the preparation of catalyst‐free vinylogous urethane foams. Room‐temperature foaming with n‐pentane generates lightweight cellular materials, while the choice of amine enables control over foam structure and mechanical properties.

Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments
We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.

Symmetrical and unsymmetrical α,ω-nucleobase amide-conjugated systems
We present the synthesis and selected physicochemical properties of several novel symmetrical and unsymmetrical α,ω-nucleobase mono- and bis-amide conjugated systems containing aliphatic, aromatic or saccharidic linkages. The final stage of the synthesis

Graded Metallopolymer Structures with Shape‐Memory Abilities via DLP‐Based 3D‐Printing
This study presents the digital light processing (DLP) based 3D printing of graded metallopolymers featuring shape‐memory abilities. The permanent shape can be recovered in two distinct steps with excellent rates. The obtained graded prints range from simple rod‐like structures to complex hollow materials.
