Organic semiconductors have received special attention as promising materials for next-generation semiconductor
electronics due to their advantages such as excellent opto-electric characteristics, easy tunability, solution-processability
and low cost of production based on mechanical flexibility.
In this presentation, a new approach to organic semiconductor materials for chiral optoelectronic devices and wearable
electronic devices will be introduced. Organic semiconductors with π-conjugated molecular structures can be programmed
by the introduction of structural asymmetry in optical chirality, and it is possible to prepare thin film structures for chiral
optoelectronic devices easily by solution processes. As a new strategy, chiroptical semiconductor films can be
successfully prepared by simple mixing of achiral polymer semiconductor and a versatile chiral small molecule.
In the development of wearable electronic technology, research is underway to realize the electronic fabric (e-textiles) that
maintain the electrical function of the device with the advantages of the fabric platform. For this purpose, development of
one-dimensional (1D) electronic devices is required. Here a device architecture for high performance fiber organic transistors
based on a double-stranded assembly of microfiber electrodes for electronic fiber applications has been proposed.
This presentation will include a description of how the device is fabricated, how to control the nanostructures of the organic
semiconductor thin films, and its correlation with optical and electrical properties of the devices.
