Molecular bridges power up printed electronics

Nanowerk  February 25, 2021 Semiconducting transition metal dichalcogenides (TMDs) can be used to make conductive inks to manufacture printed electronic and optoelectronic devices. However, defects in their structure may hinder their performance. To boost the electrical performance of TMD based devices an international team of researchers (France, Ireland, UK) has developed ‘molecular bridges’- small molecules that interconnect the TMD flakes. The molecular bridges double up as walls, healing the chemical defects at the edges of the flakes and eliminating electrical vacancies that would otherwise promote energy loss and they provide researchers with a new tool to tailor the conductivity of […]
