A. Hatano et al., Self-assembly of chelator-type nucleic acid mimics into a single-stranded Zn-II coordination polymer, CHEM LETT, (7), 2000, pp. 822-823
The synthesis of a "chelator-type" adenine mimic, which has two metal bindi
ng sites, and its Zn-II-assisted self-assembly into a single-stranded coord
ination polymer are described. The UV absorption changes of a 1 : 1 mixture
of the Zn-II complex and a single-stranded DNA oligomer (dT)(70) showed th
e temperature-dependent hyperchromic effect in an analogous manner as therm
al denaturation processes of natural DNA duplexes.
