Description Trimethyl-(9,9,18,18-tetrahexyl-15-trimethylstannyl-5,14-dithia-9,18-disilapentacyclo[10.6.0.03,10.04,8.013,17]octadeca-1(12),2,4(8),6,10,13(17),15-heptaen-6-yl)stannane (CAS: 1569453-45-7) is a highly specialized organotin compound with the molecular formula C44H74S2Si2Sn2. This complex heterocyclic structure features dual stannane (Sn) centers, silicon (Si) bridges, and sulfur (S) heteroatoms within a rigid pentacyclic framework. The presence of hexyl side chains enhances solubility in organic solvents, while the trimethylstannyl groups serve as reactive sites for further functionalization. This compound is supplied as a high-purity solid (>95%) and is ideal for advanced applications in materials science, particularly in the synthesis of organometallic polymers or as a precursor for Stille cross-coupling reactions. Store under inert gas at -20??C to prevent degradation.

Application

This compound is primarily used as a key monomer in the synthesis of conjugated polymers for organic electronics, including organic photovoltaics (OPVs) and field-effect transistors (OFETs). Its rigid, fused-ring structure and stannyl groups enable efficient Stille coupling to construct high-performance donor-acceptor copolymers. Researchers also employ it to develop silicon- and sulfur-containing hybrid materials with tunable optoelectronic properties. The hexyl substituents improve processability without compromising charge transport characteristics.
