• Description: It has many applications such as phosphorus-free matches, dyeing, and explosives, especially an ingredient in primes for cartridges. Moreover, this chemical can also act as an effective agent for enhancing the performance of perovskite solar cells. For example, planar perovskite solar cells exhibit a reduced hysteresis and boosted fill factor after introducing lead thiocyanate additive.1 Using this additive, the improved performance is further verified in the formamidinium and cesium lead triiodide perovskite solar cells.2 In addition, antigen retrieval can be realized by microwave irradiation in lead thiocyanate.3 Besides, an efficient stereoselective 1,2-dithiocyanation of various alkynes has been accomplished by employing this chemical as a reagent.4
• Uses: Reverse dyeing with aniline black; manufacture of safety matches and cartridges. 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.
