Deactivation Mechanism

Excited-state deactivation mechanism of protonated cytosine and thymine is investigated based on ab initio and NAMD simulation methods. The ring deformation from C6 region is suggested to play the most prominent role in deactivation mechanism.

Protonated Cytosine

A new approach has been explored to detect i-motif DNA structures over its complementary GQ DNA based on the hemi-protonated cytosine–cytosine (C+–C) base pairing recognition. This approach also shows its versatility by detecting various i-motif DNA structures with different chain lengths, molecularity and sizes, etc.
