Contemporary Applications of Chemical Libraries for Drug Discovery and Methods for Their Synthesis

open access: yesChemistryEurope, Volume 4, Issue 5, May 2026.
Screening of chemical libraries has over the past decades become a cornerstone of drug discovery. Today, a broad range of chemical libraries exist but they are often not well described in terms of diversity. This review describes current efforts which aim to visualize chemical diversity in compound collections and discuss current trends in synthetic ...

Chemical Upcycling of Nitrile Butadiene Rubbers to Polyamines and Polyols by Chemoselective Catalytic Hydrogenation

open access: yesAngewandte Chemie, Volume 138, Issue 18, 27 April 2026.
We demonstrate here the transformation of NBR (Nitrile butadiene rubber) including post‐consumer waste sourced from nitrile gloves and o‐rings into polyamines and polyols via ruthenium catalyzed hydrogenation. ABSTRACT We report here two new approaches for the chemical recycling/upcycling of nitrile butadiene rubber (NBR) to make either polyamines or ...

Scratch‐Healing of Conjugated Polymers: Flexibly Linked PTB7‐Th Copolymers and Their Blends

open access: yesMacromolecular Chemistry and Physics, Volume 227, Issue 9, 15 May 2026.
Flexibly‐linked conjugated polymers based on the donor polymer PTB7‐Th are capable of scratch healing. A higher linker content leads to higher “mobility,” which is required for the healing process. However, the optical properties are impaired. Blends of donor polymers with high and low linker content can solve this dilemma as they provide sufficient ...

Acceptorless Dehydrogenative Polymerization

open access: yesAngewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Acceptor‐less dehydrogenative polymerization (ADP) enables the atom‐economic step‐growth synthesis of different type of polymers directly from simple alcohols, releasing H2 as the sole by‐product. This review outlines the mechanistic foundations, catalytic systems, and emerging polymer architectures of ADP, highlighting its potential as a sustainable ...

Bio‐Based Polyurethanes: Mechanical Performance, Structure–Property Relationships, and Future Directions

open access: yesJournal of Polymer Science, Volume 64, Issue 9, Page 1860-1894, 1 May 2026.
This review examines bio‐based polyurethanes from renewable feedstocks, focusing on structure‐property relationships governing mechanical performance. It analyzes reinforcement strategies, benchmarks against petrochemical counterparts, and explores future directions, including non‐isocyanate routes and circular economy integration for sustainable high ...
