A novel biferocene trinuclear complex for Schiff base ligand S-methyl-N- (ferrocenyl-1-methyl -methylidene) dithiocarbazate thereafter abbreviated as HL) is described. X-ray diffraction studies established the structure of the palladium complex, PdL2. The geometry of Pd (II) in the complex is close to square planar and in novel cis-configuration with two ferrocene moieties on the same side. Degenerate four-wave mixing (DFWM) measurements show that the complex exhibit obvious nonlinear optical response.

A novel Schiff base ligand (HL) derived from S-methyldithiocabazate and pmethoxylbenzaldehyde was prepared and characterized. The Schiff base ligand acts as a single negatively charged bidentate ligand fondng D-M-D type comPlex (D=donor, M=metal). Single crystal X-ray diffraction analysis of the copper(Ⅱ) complex established that the geometry around Cu (Ⅱ) is square-planar with two equivalent M-N and M-S bonds. The two phenyl rings and the coordinated plane are almost in one plane fotheng an electronic delocalization system. Their thirdorder response was also studied.

Constructing type II heterostructures represents a widely recognized strategy for enhancing charge separation and photocatalytic efficiency,but it remains challenging to fabricate homologous heterostructures based on visible-light-responsive semiconductors,especially for popularly investigated （oxy）nitrides with low thermal ***,we synthesized a homologous heterostructure （denoted as YTON＿H） based on the oxynitrides of YTaO4-xNyand YTa *** heterostructure exhibits type II band structure alignment and intimate interface achieved through a magnesium （Mg） powder-assisted nitridation *** with widely reported heterologous heterostructures,the as-obtained YTON＿H homologous heterostructure could similarly exhibit enhanced charge separation as well as photocatalytic water splitting performance with respect to its counterparts(YTaO4-xNyand YTaON2).Meanwhile,detailed structural characterizations and spectroscopy analysis have been made to confirm the formation of heterostructure and promotion of spatial charge separation.

A novel macrocycle containing thiophene （L） was prepared first by the interaction of 2,5-bis-（chloromethyl）-thiophene （A） and salicylaldehyde to give 2, 5-bis-（2-formylphenoxymethyl）-thiophene （B）, and then by the nontemplate cyclocondensation of 1,3-diaminopropane with （B） followed by a "onepot" reduction without isolation of the diimine intermediate. The corresponding silver complex, AgLClO;, was also prepared. The macrocycle was characterized by IR, elemental analysis, MS and;HNMR.
