Two vanadium(V) complexes derived from the bromo and chloro-substituted hydrazones N'-(4-bromo-2-hydroxybenzylidene)- 2-chlorobenzohydrazide (H2L1) and N'-(3-bromo-5-chloro-2-hydroxybenzylidene)-3-methylbenzohydrazide (H2L2) with the formula [VOL1(OCH3)(CH3OH)] (1) and [VOL2(OCH3)(CH3OH)] (2) were newly synthesized and characterized by IR, UV-Vis and 1H NMR spectroscopy. The structures of H2L1
Herein, instant and precise control of fluorescent emission color and transmittance could be carried out by ultrasound-promoted gel-to-gel transition of naphthalimide derivatives containing CN unit. It is proved that ultrasound triggered an irreversible and efficient configuration transformation of N1 from
