摘要：
A new class of pi-conjugated organic fluorophores containing a 6H-phenanthro [4,5-cde]pyreno [4',5':4,5]imidazo [1,2-a]-azepin-6-one core was synthesized by a facile one-pot condensation method. The molecular structures and solid-state packing properties of these compounds were investigated by X-ray single crystallographic analysis. UV-vis absorption and fluorescence spectroscopic studies disclosed interesting mechanofluorochromic properties in the solid state and highly sensitive acidochromic behavior in the solution phase.
