Abstract

Herein we designed hydroxy-substituted dibenzo[j,l]fluoranthenes as novel chromic compounds and evaluated their halochromic properties by UV-vis and fluorescence spectroscopy. Under basic conditions, the 1-hydroxy derivatives show hyperchromic shift, whereas the 9-hydroxy derivatives show bathochromic shift and fluorescence although the skeleton of chromophore is same. Density functional theory (DFT) calculations indicated that the different chromic properties are attributed to the difference in their resonance structures.
