Stimuli-responsive luminescent materials, which are dependent on changes in physical molecular packing modes, have attracted more and more interest over the past ten years. In this study, 2,2-dihydroxy-1,1-naphthalazine was synthesized and shown to exhibit different fluorescence emission in solution and solid states with characteristic aggregation-induced(More)
A chemosensor, 2,2′-(1,4-phenylenedivinylene)bis-8-acetoxyquinoline (1), its fluorescent sensing behavior toward representative alkali ions (Na+, K+), alkaline earth ions (Mg2+, Ca2+), and transition-metal ions (Ni2+, Cu2+, Zn2+, Hg2+, Pb2+, Cd2+) was intensively investigated. The compound (1) exhibited pronounced Hg2+ selective on–off-type fluoroionophoric(More)
In the title complex, [Cu(C(20)H(13)N(2)O)(2)], the Cu(II) ion is tetra-coordinated by an N(2)O(2) set of two ligands in a distorted recta-ngular-planar geometry. The dihedral angle between the two coordinated five-membered metalla rings is 37.5 (3)°. The mol-ecular configuration is stabilized by two C-H⋯O and two C-H⋯N intra-molecular hydrogen bonds.
