Paradigm shift in wearable bioelectronics: Drift‐free organic field‐effect transistor biosensors enabled by diode‐connected pairs

BMEMat, EarlyView.
Organic field‐effect transistor (OFET)‐based biosensors are promising for wearable technology due to their flexibility and low cost, but their susceptibility to signal drift from mechanical stress and environmental factors remains a challenge. Here, we highlight a novel strategy that eliminates these drifts through a fundamental redesign of the OFET ...

Controlling aggregation of diketopyrrolopyrroles in water

Dyes and Pigments
[Abstract] Charge repulsion can be used to control and fine tune the supramolecular aggregation of amino acid substituted diketopyrrolopyrroles in water. This is a simple method to access a number of different aggregation states with distinct photophysical properties without the need for extensive synthetic tuning, process engineering, or solvent ...

N-Annulation of the BTI Rylene Imide Organic Building Block: Impact on the Optoelectronic Properties of π-Extended Molecular Structures

Colorants, 2022
Benzothioxanthene imide (BTI) has recently emerged as an interesting and promising block for organic electronics. In this contribution, we report on the impact of the N-annulation of the latter dye on the optoelectronic of π-extended molecular structures.
