Discrete molecular complex, one and two dimensional coordination polymer from cobalt, copper, zinc and (E)-4-hydroxy-3-((quinolin-8-ylimino)methyl)benzoic acid: Synthesis, structures and gas sensing property [PDF]

open access: yesPolyhedron, 2016
Abstract(E)-4-hydroxy-3-((quinolin-8-ylimino)methyl)benzoic acid, (H2L), was synthesized and employed in the synthesis of metal complex or coordination polymers (CPs) namely, [Co(HL)2]NO3_3DMF, 1, {[Cu(L)(H2O)]_H2O}n, 2, and {[ZnL]_DMF}n, 3. Compounds have been characterized by CHN analysis, 1H NMR and IR and UV–Vis spectroscopy. Structures of 1, 2 and

Fast and efficient synthesis of high molecular weight poly(epsilon‐caprolactone) diols by microwave‐assisted polymer synthesis

open access: yesJournal of Applied Polymer Science, 2011
AbstractBecause of advantageous features such as shorter reaction times, greater yields, limited generation of by‐products and relatively easy and straightforward scale‐up, microwave‐assisted synthesis has become a very appealing tool in organic synthesis.
