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.
