Transient Current Responses of Organic Electrochemical Transistors: Evaluating Ion Diffusion, Chemical Capacitance, and Series Elements

open access: yesAdvanced Functional Materials, EarlyView.
This work establishes a general theory of the current transient of ionic‐electronic transistors under a step of gate voltage. The dominant effect is a transient charging of the channel by diffusion of ions. The additional influence of electrolyte capacitance and resistance splits the fundamental time constant of diffusion into two different components.

Analyzing Electronic Excitations and Exciton Binding Energies in Y6 Films

open access: yesAdvanced Functional Materials, EarlyView.
The Y6 molecule is used for increasing the efficiency of organic solar cells. The exciton binding energy is calculated for ensembles of Y6 molecules that are representative of the typically used films. The calculations show that the excitons typically spread out over many molecules.

Wetting of Surface Grafted Hydrophilic‐b‐Hydrophobic Block Copolymer Brushes

open access: yesAdvanced Functional Materials, EarlyView.
The wetting properties of surface grafted diblock copolymer brushes are influenced by the thickness of the hydrophilic bottom block and the hydrophobic top block. The surface adapts in presence of water and the contact angles of the bottom block shine through. Abstract The wetting of diblock copolymer brushes by water is studied.
