N-substituted pyridino-based congeners of Ebselen, named here as Pyrselen, incorporating proximal Se and N atoms, undergo dimerization in solution and in the solid state through a dual donor-acceptor arrangement of chalcogen bonding sites. Dimerization constants were measured within the 15-50 M–1 range. Computational studies on the dimers depict a notable charge-transfer contribution to the association, validating Pyrselen as an effective scaffold for designing chalcogen-bonding-based recognition motifs.

溶液中的双硫族键合识别阵列


Ebselen 的 N 取代吡啶基同系物（此处命名为 Pyrselen）包含邻近的 Se 和 N 原子，通过硫族键合位点的双供体-受体排列在溶液和固态中进行二聚化。在 15-50 M–1 范围内测量二聚常数。对二聚体的计算研究描绘了对这种关联的显着电荷转移贡献，验证了 Pyrselen 作为设计基于硫族键的识别基序的有效支架。在此插入抽象文本。
