合成了L-精氨酸蒽衍生物1,考察了碱土及过渡金属离子对主体分子1荧光光谱的影响,结果发现,在中性水溶液条件下只有Cu2+能有效地猝灭其荧光.另外,通过OH-/H+和Cu2+/乙二胺四乙酸(EDTA)均能对化合物1的荧光强度进行可逆性调控.在此基础上,我们以化合物1水溶液作为起始状态,以OH-和Cu2+为两化学输入,构建了一个“或非”(NOR)分子逻辑门;以1-Cu2+水溶液体系作为起始状态,以H+和EDTA为两化学输入,构建了一个“或”(OR)分子逻辑门.
Synthesis of L-arginine anthracene derivatives 1, investigated alkaline earth and transition metal ions on the fluorescence spectra of the main molecule 1 and found that in the neutral aqueous solution conditions, only Cu2 + can effectively quench its fluorescence.In addition, by OH- / H + and Cu2 + / ethylenediaminetetraacetic acid (EDTA) were able to reversibly control the fluorescence intensity of compound 1. On this basis, we started with compound 1 aqueous solution, with OH- and Cu2 + as two Chemical input, a “NOR” molecular logic gate was constructed. A 1-OR2 (OR) was constructed by starting with 1-Cu2 + Molecular logic gate.
