compound that could be cyclized to N-protected aza-macrocycle. After a smooth deprotection step, the macrocycle was alkylated with chloroacetic acid leading to the pyridine containing triaza-macrocycle 1 in good yield. The luminescence properties of its Eu3+ complex were examined in aqueous solution.
二亚乙基三胺与2-硝基苯磺酰氯的反应产生活化和受保护的化合物,其可以环化为N-保护的氮杂大环。在平稳的脱保护步骤之后,将大环用氯乙酸烷基化,以高收率得到含吡啶的三氮杂-大环化合物1。在水溶液中检查其Eu 3+配合物的发光性质。
