Organolead compounds are organic substances whose molecular structure includes lead. Because of these compounds' wide range of uses in organic synthesis, materials science, and catalysis, they have been well researched. However, because of worries about lead toxicity's effects on the environment and human health, their use has drastically decreased recently. Organolead halides, which are composed of lead bound to halogen atoms like chlorine, bromine, or iodine, are one class of organolead compounds. The potential of these compounds as photovoltaic materials in solar cells has been studied. In particular, lead halide perovskites have drawn interest because of their effective charge transport capabilities and high light absorption coefficients. Organolead carboxylates, a significant subclass of organolead chemicals, are composed of lead bonded to carboxylic acid groups. These substances have been used as catalysts in reactions involving organic synthesis, namely in the creation of carbon-carbon bonds. Furthermore, the possible use of organolead carboxylates as heat stabilizers in the stabilization of polyvinyl chloride (PVC) has been investigated. In order to increase the thermal and oxidative stability of lubricating oils, organolead compounds have also been used as additives. These substances function as antioxidants, scavenging free radicals and halting the oil's deterioration at high temperatures. However, because lead-containing compounds are restricted by environmental rules, their use in this application has decreased. Even with their wide range of uses, organolead compounds are hazardous to the environment and human health. Lead is a heavy metal that is extremely poisonous and can build up in the environment and in living things. This can have serious health implications, including aberrant development and neurological diseases. Because of this, a deliberate effort has been made to gradually stop using lead-containing substances, such as organolead compounds, in a variety of applications.To sum up, organolead compounds are a type of organic compounds that contain lead and have been applied in a number of fields, such as materials science, lubricant additives, and catalysis. However, their use has decreased in favor of substitute substances with less detrimental effects due to their toxicity and environmental concerns. Research is still ongoing. to investigate more environmentally friendly and secure substitutes for organolead compounds in a range of applications.
