Description
This poster examines organic semiconductors which are growing in application for utilization in modern technology such as solar panels, electronic devices, and printers. The main interest in these organic compounds is their low cost (compared to silicon, a commercial semiconductor) and flexibility. Organic semiconductors are characterized by several integral traits including, but not limited to extended conjugation, coplanarity of the entire molecule, and narrow band gap. Bibenzothiophene (BBT) which was used as a precursor for our experiment is an example of an organic semiconductor. This research seeks to further synthesize, analyze, and understand the effect of linking aromatic phenyl- and thienyl groups to the BBT core on band gap energies. Low band gap energies are a desirable trait in organic semi-conductors. The synthesis can be divided into two parts: Part 1: the synthesis of brominated BBT. Part 2 describes various reactions with brominated BBT generating various side groups. Three products were synthesized successfully with about 80% yield, and two reactions were attempted but were unsuccessful. The obtained products varied in color, which indicated a change in band gap energies. Further analysis of the obtained products (NMR and X-ray analysis), and the resynthesis of some compounds are to be performed in the future.
