Application

Reactant involved in synthesis of:
  • Organic field-effect transistors based on organic semiconductors containing diazaboroles
  • Cycloparaphenylenes via Suzuki coupling
  • 1,3,2-Diazaboroine derivatives for organic thin-film transistor applications
  • Back-to-back coupled 2,6-bis(triazol-1-yl)pyridine molecules
  • Rectangular host via electrochemical reactions with methylaquacobaloxime and diamine
  • Arylboronates from reactions with catechol, dihydroxynaphthalene and diaminobenzenedithiol for use as organic field-effect transistors and light emitting diodes
