Crystal engineering of alkylethynyl fluoroanthradithiophenes

2-Dimensional brickwork packing is desirable for high mobility organic semiconductors. We synthesised acene derivatives that adopt this packing without using heavier group 14 elements to investigate substituent effects on bulk transport properties.

Conjugated polyelectrolyte-based ternary exciton funnels via liposome scaffolds

We used a vesicle scaffold to form a ternary, quasi-panchromatic funnel for electronic excited states oriented from the outer surface towards the membrane. We did so via electronic energy transfer (EET) from two conjugated polyelectrolytes to a phthalocyanine.

Development of hybrid coarse-grained atomistic models for rapid assessment of local structuring of polymeric semiconductors

A model of semiconducting polymers where the conjugated portion is described with atomistic detail and the alkyl side chains are approximated with a coarse grain potential is very promising for the molecular design of new polymeric materials.

Dynamic processes in transient phases during self-assembly of organic semiconductor thin films

Crystallization of organic semiconductor small molecules from solution proceeds in multiple steps. This study describes how asymmetric molecules lead to long-lived transient phases and their impact on carrier mobility for electronic devices.

About this collection

This collection, Guest Edited by Ying Diao (University of Illinois at Urbana-Champaign) and Dean DeLongchamp (National Institute of Standards and Technology), aims to showcase the latest cutting-edge research into the molecular engineering and controlled assembly of organic molecular electronic materials.
The assembly process is critical to controlling the multiscale morphology of organic electronics from molecular conformation and packing, mesoscale domain size and orientation, and macroscale alignment. Such multiscale assembly process sensitively modulates device properties of thin film transistors and conductors, thermoelectrics, mixed conductors, solar cells and sensors to name a few. However, much is unknown about how molecular electronics assemble and their phase behaviors in the solution and solid state. This poses challenges for precisely controlling and modulating their multiscale morphology and establishing structure-property relationships. In addition, the assembly pathways can be drastically modulated by the additive manufacturing process, which present new opportunities for tuning assembly process. Processing often drives assembly far from equilibrium, to create a new frontier of non-equilibrium assembly for the field of organic electronics.
Articles are added as soon as they are published.
