Ancillary Ligand-Mediated Syntheses, Structures and Fluorescence of Three Zn/Cd(II) Coordination Polymers Based on Nitrobenzene Dicarboxylate
The Zn/Cd(II)-nbdc carboxylate motifs mediated by various dipyridyl-typed ligands afforded three new coordination compounds, namely, [Zn(nbdc)(bpa)0.5(H2O)]·H2O (1), [Zn2(nbdc)2(bpp)2]·H2O (2), and
Synthesis, Characterization and DFT Studies of Two New π-conjugated Pyridine-based Tetrathiafulvalene Derivatives
Two new π-conjugated pyridine-based tetrathiafulvalene derivatives, 2-(2- (4,5-bis(methylthio)-1,3-dithiol-2-ylidene)-6-phenyl-[1,3]dithiolo[4,5-b][1,4]dithiin-5-yl)pyridine ( 2a ) and

It is found that the absorption at 240 and 365 nm are observed in the UV spectrum of PPA and the absorbed at 210 nm is the only one in BPPA, demonstrating that PPA has the olefinic alcohol structure and BPPA hasn't.
Synthesis, characterization and DFT studies of two new pi-conjugated-conjugated pyridine-based tetrathiafulvalene derivatives.
Two new pi-conjugated pyridine-based tetrathiafulvalene derivatives, 2-(2- (4,5-bis(methylthio)-1,3-dithiol-2-ylidene)-6-phenyl-[1,4]dithiin-5-yl)pyridine and 2b, have been synthesized and characterized by 1H NMR, elemental analysis and mass spectroscopies.
