摘要
埃布塞伦的 N-取代吡啶同系物（此处命名为 Pyrselen）含有近端 Se 原子和 N 原子，在溶液和固态中通过双供体-受体排列的查尔根键位发生二聚反应。二聚常数的测量范围为 15-50 M-1。对二聚体的计算研究表明，电荷转移对二聚体的结合有显著的促进作用，从而验证了派尔塞伦是设计基于查尔根键的识别图案的有效支架。此处插入摘要文本。
Double Chalcogen Bonding Recognition Arrays in Solution
N-substituted pyridino-based congeners of Ebselen, named here as Pyrselen, incorporating proximal Se and N atoms, undergo dimerization in solution and the solid state through a dual donor-acceptor arrangement of chalcogen bonding sites. Dimerization constants were measured within the 5–50 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.
