• 10.3762/bjoc.15.278 Abstract A novel anthracene-based tetraperimidine hexafluorophosphate 3 was prepared, and its structure was determined through X-ray analysis, HRMS as well as 1H and 13C NMR spectroscopy. In the cationic moiety of 3, two (N-ethylperimidinyl–C2H4)2NCH2– arms were attached to the 9- and

• ; chromium(III) ion; tetraperimidine; Introduction Fluorescent chemosensors are an attractive and efficient tool for the detection of metal ions in environmental and biological science because of their high sensitivity, selectivity, and simple usage [1][2][3][4][5][6][7][8]. Among metal ions, the detection

In this paper, we report the synthesis of a novel anthracene-based tetraperimidine hexafluorophosphate 3, and its structure was determined by
