Abstract: Abstract Novel 5,6,5,6-tetracyclic pyrazine/pyrrole-fused unsymmetric bis(BF2) fluorescent dyes (BOPYPYs) were obtained by reaction of pyrrole-2-carboxaldehyde with 1-(pyrazin-2-yl)hydrazine in the presence of Et3N-BF3·Et2O for the first time. The absorption maxima of pyrazine-fused BOPYPY are obviously bathochromic… read more here.
