  Synthesis of nucleobase-calix[4]arenes via click chemistry and evaluation of their complexation with alkali metal ions and molecular assembly

  摘要：

  In this study, calix[4] arene derivatives (11 14) bearing a single nucleobase (adenine, thymine, cytosine or guanine) were synthesised via click chemistry. The complexation ability of the synthesised derivatives with alkali metal ions was measured using MALDI-TOF mass spectrometry, and their molecular assembly in CDCl3 was determined using H-1 NMR. Calix[4] arene derivatives (11-14) formed 1: 1 complexes with all alkali metal ions and the rank order for the complexation selectivity was Rb+ > Cs+ > K+ congruent to Na+ > Li+. The attachment of nucleobase at the upper rim of calix[4] arene had little effect on its complexation selectivity for alkali metal ions. Thymine-, adenine-and guanine-calix[4] arenes formed self-assembled structures in CDCl3 via base-base interactions. In addition, adenine-calix[4] arene (11) bound to thyminecalix[4]arene (12) to form a discrete species via Hoogsteen hydrogen bonding.
