Application

Bis(trifluoromethane)sulfonimide lithium salt (Li-TFSI) can be used:
  • As a chemical additive for improving the power conversion efficiencies in porphyrin-based organic solar cells.     
  • As a reagent in the preparation of imidazolium core bearing monomer ionic liquids to develop polymerized ionic liquids.
  • For the preparation of a chiral imidazolium salt via anion metathesis of the corresponding triflate.       
  • In the synthesis of solid polymer electrolytes for lithium-ion batteries. 
  • In the synthesis of polyelectrolyte reusable homogenous catalysts, which are used in the Diels–Alder reactions between isoprene and a variety of dienophiles.
  • Used in the preparation of electrolytes for lithium batteries and novel rare-earth Lewis acid catalysts.

Two new conjugated acceptor-π-donor-π-acceptor (A-π-D-π-A) porphyrins have been synthesised using 3-ethylrhodanine (1a) or dicyanovinylene (1b) groups as acceptor units. Their optical and electrochemical properties made these materials excellent electron donors along with PC71BM as the acceptor for solution-processed bulk heterojunction
