Using anisotropic thermal expansion in organic semiconductor thin films. This project aims to capitalise upon the recent discovery of negative thermal expansion in high-performance organic semiconductor films. Certain molecules’ chemical structures have a planar conjugated core and flexible sidechains. When highly anisotropic thermal expansion occurs, the sidechains take up most of the thermal expansion.

This project aims to capitalise upon the recent discovery of negative thermal expansion in high-performance organic semiconductor films. Certain molecules’ chemical structures have a planar conjugated core and flexible sidechains. When highly anisotropic thermal expansion occurs, the sidechains take up most of the thermal expansion. When a negative thermal expansion occurs, the pi-pi stacking distance decreases upon annealing. This effect has been linked with higher charge mobilities, and a tighter molecular packing is locked in upon cooling. The potential applications of these high performance organic semiconductors includes chemical/biosensors, electronic paper, and radio frequency identification cards.Read moreRead less
