Abstract:Electron-rich
1,5-dialkoxynaphthalene (DAN) and electron-deficient
1,8,4,5-naphthalenetetracarboxylic diimide (NDI) are known to interact
through the formation of charge-transfer complexes. The introduction
of DAN and NDI into various DNA duplexes and hairpins was investigated
by ultraviolet (UV) melting curve analysis. The positioning of the
DAN:NDI pair was found to strongly influence the stability of DNA
duplex and hairpins. In particular, while the introduction of one
DAN/NDI pair in front of each other in… Show more
