Metal-free organic photosensitizers are widely used in dye-sensitized solar cells(DSCs),of which D-π-A molecules with aromatic amine as electron donor(D) represent one of the most important types.

A series of D-π-A molecules, containing pyrrolidine group as electron donor and cyano acetic acid, formacyl, diethyl cyanomethyl phosphonate groups as electron acceptor covalently attached to thienylenevinylene π-conjugated bridges, are synthesized and their photophysical and electrochemical properties are studied.

A supramolecular compound [Ni(C6H4O2N)2(H2O)4] was synthesized by the reaction of Ni(NO3)26H2O and isonicotinic acid through hydrothermal method.

The supramolecular compounds with ligand of pyridine-3- sulfonate were prepared .

The supramolecular systems of meso-tetrakis(4-pyridyl)porphyrin(TPyP) with α-cyclodextrin(α-CD),β-CD,γ-CD,SBE-β-CD and TM-β-CD were examined by absorption and fluorescence spectroscopy in NH3-NH4Cl buffer solution(pH 10.

The supramolecular systems of water-soluble porphyrin, meso-terakis(4-methoxyl-3-sulfonato-(phenyl)) porphyrin(T(4-Mop)PS_(4)),with five cyclodextrins(CDs),including α-,β-,γ-cyclodextrin(α-CD,(β-CD),γ-CD),hydroxylpropyl-β-CD(HPβ-CD),sulfurbutylether-β-CD(SBE-β-CD),have been studied by polarography,ultraviolet spectrometry and fluorescence spectrometry.

The supramolecular systems of water-soluble porphyrin(TPPS_4) with HP-γ-CD, HP-α-CD have been studied by electrochemistry method.
