Mimicking Block Copolymer Self‐Assembly with One‐Pot Synthesized Polyphosphoester Gradient Copolymers

Advanced Functional Materials, EarlyView.
Degradable Polyphosphoester (PPE) gradient copolymers (GCPs) are synthesized via one‐pot copolymerization. We show that GCPs self‐assemble into nanostructures like polymersomes, effectively mimicking the behavior of traditional BCPs. The gradient strength is key, with softer gradients favoring micelles.

Electric Field‐Dependent Conductivity as Probe for Charge Carrier Delocalization and Morphology in Organic Semiconductors

Advanced Functional Materials, EarlyView.
Applying a high electric field to a doped organic semiconductor heats up the charge carrier distribution beyond the lattice temperature, enhancing conductivity. It is shown that the associated effective temperature can be used to extract the effective localization length, which is a characteristic length scale of charge transport and provides ...

Radiation Effects in Electret Organic Thin‐Film Transistors Due to High Flux and High Dose X‐Ray Irradiation

Advanced Materials, EarlyView.
Electret‐style organic thin‐film transistors are evaluated for synchrotron X‐ray dosimetry at ultra‐high dose rates, showing promising performance and agreement with standard detectors. XPS and NEXAFS reveal radiation‐induced oxidation and Fermi level shifts in pentacene and polystyrene, correlating with reduced charge carrier mobility and providing ...

Monte Carlo study of the molecular organization in model nematic droplets. Field effects

Chemical Physics Letters, 1992
Abstract The Monte Carlo technique is used to investigate the orientational order and the molecular organization of model nematic droplets with radial boundary conditions subject to an external field. The effect of varying field strength on these model systems of polymer dispersed liquid crystals (PDLC) is also investigated.

Molecular Surface Engineering of Sulfide Electrolytes with Enhanced Humidity Tolerance for Robust Lithium Metal All‐Solid‐State Batteries

Advanced Materials, EarlyView.
It is demonstrated that the electrochemical, interfacial, and humidity stability of halide‐doped sulfide electrolytes (LPSClBr) is significantly enhanced by an organic surface coating using octadecyl phosphonic acid (OPA) and its lithiated form (Li‐OPA). This single‐step strategy enables robust interfacial protection, supports lithium metal anodes, and

Hopping and microscopic dynamics of ultrasoft particles in cluster crystals

, 2010
We have investigated the slow dynamics of ultrasoft particles in crystalline cluster phases, where point particles interact through the generalized exponential potential u(r) = \epsilon \exp[-(r/\sigma)^n], focusing on the cluster fcc phase of this model
