Molecular flexibility tuned emission in “V” shaped naphthalimides: Hg(ii) detection and aggregation-induced emission enhancement (AIEE)

Abstract

Four "V" shaped 1,8-naphthalimides (1-4) have been synthesized and their fluorescence quantum-yields correlated to their molecular flexibility. The correlation was used for detection of Hg(II) via a chemodosimetric approach. was found to be an AIE active molecule with the formation of fluorescent nanoaggregates.
