Semiconducting Polymers Post‐Functionalized With Ureido‐Pyrimidinone for Robust Stretchable Transistors

open access: yesAdvanced Functional Materials, EarlyView.
The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable

Biomimetic Microfractals Based Flexible Triboelectric Nanogenerators

open access: yesAdvanced Functional Materials, EarlyView.
A leaf‐skeleton‐based microfractal architecture is integrated with guided CuNW networks and biomimetic triboelectric polymer layers, enabling breathable, flexible, and material‐efficient triboelectric nanogenerators. The resulting system combines enhanced charge generation and charge transport, offering potential for next‐generation self‐powered ...

High‐Performance n‐Type Organic Thermoelectrics Enabled by Control Over Microstructure, Orientation and Contact Plane in Naphthalenediimide‐Bithiazole‐Copolymer Films

open access: yesAdvanced Functional Materials, EarlyView.
Effective control over the crystalline contact plane and microstructure of a naphthalenediimide‐bithiazole copolymer enables high‐performance n‐type thermoelectrics. While rubbing alignment induces a detrimental edge‐on orientation, subsequent solvent vapor‐induced re‐orientation facilitates a favorable mixed face‐on/edge‐on morphology.

Biomineral‐Inspired Organic/Inorganic Colloidal Liquid‐Crystalline Hybrids for Photoresponsive Adhesion

open access: yesAdvanced Functional Materials, EarlyView.
A new class of photoresponsive liquid‐crystalline (LC) adhesives based on biomineral‐inspired organic/inorganic colloidal hybrids is reported. These colloidal LC materials are formed by hybridization of a hydroxyapatite nanorod with azobenzene‐based forklike molecules.

Reconstructing Quantum Dot Surfaces via Dual‐Functional Ligand Pairing Enables Efficient Shortwave Infrared Optoelectronics

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a ligand‐pairing strategy that reconstructs lead sulfide quantum dot surfaces for efficient short‐wave infrared optoelectronics. A low‐reactivity thiourea precursor combined with hydrobromic acid enables monodisperse and fully passivated quantum dots.
