In this report, a new coordination complex Pb(CDIPT)2(L)2 (CDIPT= 10?chloro?2-(2,4-dichlorophenyl)-1H-imidazo[4,5-f]-[1,10]phenanthroline, HL= 2,4-dichlorophenyl acrylic acid) has been synthesized and fully characterized by elemental analysis, IR spectroscopy, UV spectrum, single-crystal X-ray diffraction analysis, luminescence spectra, TGA and powder X-ray diffraction. The structural analysis showed that the complex 1 is a zero dimensional structure with seven coordinated Pb(II) ion. And further, the adjacent complex units are extended into a 2D supramolecular network through the H-bonds [N(4)-H(4)???O(4) and N(7)-H(7)???O(1)]. The luminescence explorations demonstrated that complex 1 has good optical properties. In addition, the quantum chemistry calculations were performed with the Gaussian09 program.

Paragraph 0114-0116, (2019/10/22)
The invention provides a cinnamic acid derivative. The cinnamic acid derivative is of the structure as shown in the formula I. The invention also provides two methods for preparing the cinnamic acid derivative. The two methods depend on a single bond or double bonds in the structure shown in the formula I. The invention further provides a pesticide. The pesticide comprises the cinnamic acid derivative. In addition, the invention provides a sterilization method. The sterilization method includes the step of applying the cinnamic acid derivative or the pesticide to crops. The crops include rice,wheat, fruit trees and vegetables. The low-toxicity, low-residue-content and high-activity environment-friendly cinnamic acid derivative is developed, and the cinnamic acid derivative pesticide can replace traditional high-toxicity and high-residue-content pesticides.

A series of novel 11-O-carbamoyl clarithromycin ketolides were designed, synthesized and evaluated for their in vitro antibacterial activity. The results showed that the majority of the target compounds displayed improved activity compared with references against erythromycin-resistant S. pneumoniae A22072 expressing the mef gene, S. pneumoniae B1 expressing the erm gene and S. pneumoniae AB11 expressing the mef and erm genes. In particular, compounds 9, 18, 19 and 22 showed the most potent activity against erythromycin-resistant S. pneumoniae A22072 with the MIC values of 0.5?μg/mL. Furthermore, compounds 11, 18, 19, 24 and 29 were also found to exhibit favorable antibacterial activity against erythromycin-susceptible S. pyogenes with the MIC values of 0.125–1?μg/mL, and moderate activity against erythromycin-susceptible S. aureus ATCC25923 and B. subtilis ATCC9372.
