Abstract

We report the synthesis and characterization of iptycene-naphthazarin dyes by using a sequential Diels-Alder approach. The tautomerization of naphthazarin was used as the key step in the synthesis, with structures confirmed by single-crystal X-ray and NMR analysis. The systematic trends in electronic properties were investigated by UV/Vis spectroscopy BF2 complexes of the dyes were prepared by reaction with BF3 OEt2 in CH2Cl2.
