Synthesis of organic nanowires for stretchable, flexible and twistable devices

Organic semiconductor nanowires were fabricated using conjugated polymer — 14H-benzo[4,5]isoquinolino[2,1-a]perimidin-14-one (IPN). UV-vis absorption and photoluminescence spectroscopy were used to determine the orientation of IPN aggregation to determine the feasibility of its potential purpose as...
