High Electron Charge Carrier Mobility in the Nematic Phase of a Roof‐Shaped Nematogen with Optimum Molecular Biaxiality

open access: yesAdvanced Science, EarlyView.
Liquid Roofs. Biaxial roof‐shaped mesogens self‐assemble in a nematic phase of a broad temperature range exhibiting high TOF electron mobilities. These mesogens possess the almost optimum biaxial aspect ratio. The results from X‐ray, polarized optical microscopy, modeling, and TOF data agree with biaxiality of small domains and transient nematic phase ...

Layer‐By‐Layer Approach to Improve the Capacitance of Conducting Polymer Films

open access: yesAdvanced Electronic Materials, EarlyView.
This work describes the synthesis and characterization of a composite material based on poly(3,4‐ethylenedioxythiophene) (PEDOT) and poly(3,4‐ethylenedioxypyrrole) (PEDOP) deposited in a layer‐by‐layer approach. Due to the developed electroactive area coming from the presence of 3D nanostructures, PEDOT/PEDOP demonstrates superior areal capacitance ...
