| 英文摘要 | A naphthalene-barbiturate conjugant (g-np) and a pockety barbiturate receptor (hamilton receptor, h-receptor) with two 2,6-diaminopyridine groups linked through an isophthalic acid spacer were synthesized. the dyad is created by functionalizing the h-receptor and g-np with six hydrogen bonds, which provide a high apparent association constant (k(app) approximately equal to (4.9 +/- 0.5)x 10(4) mol(-1).l in ch(2)cl(2)). excitation with 330 nm light mainly results in a singlet electron transfer between naphthalene and the h-receptor at room temperature, and a triplet energy transfer from the h-receptor to naphthalene at 77 k. these findings provide a new model for the study of the hamilton hydrogen-bonded system, and will benefit understanding the role of hydrogen bonding in natural assemblies. |
