The synthesis of a 2'-deoxyuridine nucleoside linked to an anthraquinone moiety, and its incorporation into oligonucleotides are described, including a facile oxidative demethylation with phenyliodine(iii) bis(trifluoroacetate) to reveal the anthraquinone motif. Furthermore, some useful physical and electrochemical properties of the obtained oligonucleotide are also reported, which allow its pr...

In the title compound, C(3)H(12)N(2) (2+)·2ClO(4) (-)·2C(12)H(24)O(6), the central C atom of the propane-1,3-diammonium cation is located on a twofold rotation axis and the two terminal -NH(3) groups insert into the crown rings through N-H⋯O hydrogen bonding, resulting in the formation of a 1:2 supra-molecular [(C(3)H(12)N(2))·(C(12)H(24)O(6))(2)](+) complex. The perchlorate anion links with th...

The cation of the title salt, C4H14N2 (2+)·2Cl(-), is located on a crystallographic inversion center and is bis-ected by a mirror plane, with one quarter of the C4H14N2 (2+)·2Cl(-) formula unit being crystallographically unique. he chloride ions also sit on a mirror plane. The conformation of the cation is a regular straight-chain conformation with all non-H atoms in anti positions. In the crys...

Efficient initiation from ammonium trifluoroacetate salts (TFA) dendritic end-groups yields well-defined poly( l -lysine) star polypeptides with 8, 16 and 32 arms. Hydrolytic core degradation plasmid DNA complexation is demonstrated.
