photosensitize DNA damage, where one of the most relevant BP/DNA interactions occurs with thymine (Thy). In view of the complex photoreactivity previously observed for dyads containing BP covalently linked to thymidine, the aim of this work is to investigate whether appropriate changes in the nature of the spacer could modulate the intramolecular BP/Thy photoreactivity, resulting in an enhanced selectivity. Accordingly
Flipping disc networks: A discotic star shaped mesogen decorated with three DNA bases thymine reversibly switches between a columnar and an extraordinary bicontinuous cubic network. The double nanosegregated bicontinuous structure is stabilized by self-association of hydrogen bonding thymines and realize a 3D charge transport. A phase flipping is also discerned by the addition of adenine as complementary
翻转盘网络:用三个 DNA 碱基胸腺嘧啶装饰的盘状星形介晶可在柱状和非凡的双连续立方网络之间可逆地切换。双纳米分离的双连续结构通过氢键胸腺嘧啶的自缔合而稳定,并实现3D电荷传输。还可以通过添加腺嘌呤作为互补碱基来识别相翻转。
