摘要:镁(II)tetrapyrazinoporphyrazines(tpyzpzs)是优异的红色荧光团(λ ˚f〜663纳米,φ ˚f〜0.53在thf中).在这项工作中,准备了一系列带有一个或两个酚取代基的不对称tpyzpzs的镁(II)配合物.酚部分的适当取代可调节其p K A在5.5至13的范围内.酚基团在较高ph值下的去质子化会在大环中诱导强供体(酚盐),从而导致这些指示剂的红色荧光的ph依赖性猝灭.在将tpyzpzs掺入两种乳状液和脂质体两种输送系统后,水溶液中的ph感测得到了证实.后者还充当生物膜的简单模型.最后,通过将tpyzpz指示剂和亲脂性ph不敏感的bodipy染料掺入脂质体中,构建了波长比探针.Tpyzpzs的合成前体,即取代的2,3-二嗪吡嗪,也代表了供体-受体系统,肉眼很容易看到吸收光谱的ph依赖性变化.
