7‐Azaindole has been used in designing new molecular structure 1 on enediyne spacer for its application in anion sensing. New structure 1 has been established as efficient fluorescent sensor of H2PO4− and F− ions in CH3CN containing 1% DMSO. While in presence of H2PO4− the emission at 418 nm is decreased to the significant extent in nonratiometric fashion, a ratiometric response in presence of F− is noted with a sharp isoemissive point and two anions are effectively distinguished over a series of other anions tested. A similar study on model compound 2 with indole motifs is done to prove the pivotal role of extra ring nitrogen in azaindole of 1 in the binding process.

氮杂吲哚杂环修饰的新型支架的设计与合成，用于F-和H2PO4-的荧光检测
7-氮杂吲哚已被用于在二烯炔间隔基上设计新的分子结构1，以用于阴离子传感。新的结构1已被确立为H的高效荧光传感器2 PO 4 -和F -离子在CH 3 CN含有1％DMSO。而在H存在2 PO 4 - ，在418纳米的发射降低到在非比例的方式显著程度，F中的存在的比例响应-是用锋利的isoemissive点指出和两个阴离子被有效区分过一系列其他阴离子测试。模型化合物2的类似研究带有吲哚基序的化合物被用来证明在结合过程中1的氮杂吲哚中额外的环氮的关键作用。
