Molecular engineering of organic semiconductors enables noble metal-comparable SERS enhancement and sensitivity

Organic semiconductors are considered promising Surface Enhanced Raman Spectroscopy platforms. Here the authors demonstrate that metal-free films based on a π-conjugated molecule containing a fully π-conjugated backbone provides an enhancement factor of 105 and detection limit of 10−9 M for methylen...
