Application

Lead (II) thiocyanate can be used:
  • To form a complex with Schiff-base lariat crown ether, N,N′-bis(3-(salicylaldimino)benzyl)-4,13-diaza-18-crown-6.
  • To investigate complexing and fluorescence properties of calixarene bearing two dansyl fluorophores grafted on a large pore mesoporous silica material.
  • As a reagent in the 1,2-dithiocyanation of alkynes in the presence of (dichloroiodo)benzene.
  • As a precursor to synthesize perovskite films for solar cell applications.
