Synthesis and Nucleophilic Reactions of Bifunctional Thiourea S,S,S-Trioxides [PDF]
The synthesis of bifunctional thioureas and the corresponding thiourea S,S,S-trioxides has been examined. Two methods for the synthesis of the bisthioureas were employed. One involved the treatment of a diamine with silicon tetraisothiocyanate in benzene.

An efficient NiOx HTL is successfully prepared by introducing MXene as an additive without further surface modification to fabricate high‐performance FASn0.5Pb0.5I3 perovskite solar cells. The introduction of MXene contributes to improved conductivity of NiOx, better aligned at NiOx/perovskite interfaces, and enhanced quality of perovskite films ...

A cation‐anion synergistic strategy is developed to enhance self‐assembled monolayer (SAM) adsorption using guanidinium thiocyanate (GuaSCN). Guanidinium (Gua⁺) suppresses micelle aggregation, while thiocyanate (SCN−) promotes phosphonic acid deprotonation and strengthens ionic bonding to the substrate.
