Host-guest interactions of 8-aniline-1-naphthalene sulfonic acid with two macrocycles containing 2,6-pyridylamide and dipyrrole units
The host-guest interactions of two macrocycles L1 and L2 with 8-aniline-1-naphthalene sulfonic acid (1,8-ANS) were evaluated by fluorescence emission spectra. It was found that 1,8-ANS had a quenching effect upon the addition of the two macrocycles, which contain both 2,6-pyridylamide and dipyrrole units, and the corresponding binding ratios were also obtained. Furthermore, the binding behavior was investigated by H NMR titration. The results show that both the binding ratios of L1 and L2 with 1,8-ANS molecule are 1:1, and the stability constants are 3.06×104 L·mol-1 and 6.58×103 L·mol-1, respectively.
Graphical abstract
The host-guest interactions of macrocycles L1 and L2 with 8-aniline-1-naphthalene sulfonic acid were evaluated by fluorescence spectra and H NMR titration. The binding ratios of L1 and L2 with the compound are both 1:1, and the stability constants are 3.06×104 L·mol-1 and 6.58×103 L·mol-1.
期刊介绍：
Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
