Highly Fluorescent Dyes Containing Conformationally Restrained Pyrazolylpyrene (Pyrazoolympicene) Chromophore
The triflic-acid-promoted cyclization of 1-phenyl-3-(pyren-1-yl)-1<i>H</i>-pyrazole-4-carbaldehyde afforded a mixture of 9-phenyl-7,9-dihydropyreno (10,1-<i>fg</i>)indazole and 9-phenylpyreno(10,1-<i>fg</i>)indazole-7(9<i>H</i>)-one, readily separable...
