Anthracene-based ureidopyridyl fluororeceptor for dicarboxylates
摘要:
Anthracene-labelled ureidopyridyl sensor I was designed and synthesized. The emission of the sensor increased in presence of dicarboxylates. The binding properties were studied using H-1 NMR, fluorescence and UV-vis spectroscopic methods. The sensor I shows modest selectivity for 1,4-phenylenediacetate. (c) 2007 Elsevier Ltd.

previously, attempts have been made to trap the isocyanates. While the three pyridylisocyanates were trapped as their corresponding carbamates, 3-pyridylisocyanate was isolated and characterized. Unlike closely related previous methods reported for urea synthesis, the current method avoids direct use of isocyanates or eliminates the use of toxic phosgene for the in situ generation of isocyanates.
