  • A novel complex [$Zn(phen)(o-AB)_2$] [phen: 1,10-phenanthroline o-AB: o-aminobenzoic acid] was synthesized and characterized by elemental analysis and X-ray diffraction single-crystal analysis. The crystal crystallizes in monoclinic, space group P2(1)/c with $a=7.6397(6){\AA}$, $b=16.8761(18){\AA}$, $c=17.7713(19){\AA}$, ${\alpha}=90^{\circ}$, ${\beta}=98.9570(10)^{\circ}$, ${\gamma}=90^{\circ}$, $V=2.2633(4)nm^3$, Z = 4, F(000) = 1064, S = 1.058, $Dc=1.520g{\cdot}cm^{-3}$, $R_1=0.0412$, $wR_2=0.0948$, ${\mu}=1.128mm^{-1}$. The Zn(II) is six coordinated by two nitrogen and four oxygen atoms from the 1,10-phenanthroline and o-aminobenzoic acid to furnish a distorted octahedron geometry. The complex exhibits intense fluorescence at room temperature. Theoretical studies of the title complex were carried out by density functional theory (DFT) B3LYP method. CCDC: 898291.

  • Possible directions of chemical engineering education have been proposed in many studies. However, new curriculum is demanded to accommodate the special needs of our students' level and community industrial characteristics. We can think of two reasons. One is that various kinds of chemical engineering industry are found in every community. The other is that students' educational standards are different in every university. We have surveyed and analyzed jobs of our university graduates who are working in chemical company of our community Pusan and Kyoung-Nam. This study aims to develop the new curriculum with an emphasis on practical education and to propose the new direction for our major characteristic based on the survey.
