Abstract

We present herein a thoroughly study concerning synthesis, structure and fluorescent properties of two classes of pyrrolodiazine derivatives: pyrrolopyridazine respectively pyrrolophthalazine cycloadducts. The synthesis is straight and efficient, consisting in a 3+2 dipolar cycloaddition reaction of diazinium ylides to dipolarophiles with triple bound. The structure of compounds was proven by elemental and spectral analysis. The fluorescence studies reveal that the pyrrolodiazine compounds are intense blue emitters and have high quantum yield. Over all, pyrrolopyridazine cycloadducts anchored with an ester group in the 7-th position, have the best fluorescent proprieties, being very intense blue emitters and having very high quantum yields (up to 90%).
