Ferrocene-bis(thymine/uracil) conjugates: Base pairing directed, spacer dependent self-assembly and supramolecular packing

摘要

X-ray crystallographic studies of methylene linked Ferrocene-bis(thymine/ uracil) conjugates Fc(T:T)_M and Fc(U:U)_M reveal base dependent 2-D supramolecular assemblies generated via wobble self-pairing for bis-thymine and reverse wobble self-pairing for bis-uracil conjugates, differing in architecture from the corresponding butylene spacer linked conjugates
