  • Thermally stable oxadiazole-containing polyacetylenes: Relationship between molecular structure and nonlinear optical properties

    Two novel high molecular weight functional polyacetylenes bearing oxadiazole groups as pendants, poly(2-(4-decyloxyphenyl)-5-(4-ethynylphenyl)-1, 3, 4-oxadiazole) (P1) and poly(2-(4-butyloxyphenyl)-5-(4-ethynylphenyl)-1, 3, 4-oxadiazole) (P2) were designed and synthesized by a multistep reaction route. The structures and properties were characterized and evaluated with FTIR, NMR, UV, TGA, GPC, optical-limiting (OL) and nonlinear optical (NLO) analyses. The incorporation of oxadiazole into polyacetylene significantly endows polyacetylenes with higher thermal stability and optical limiting property. The solubility, stereoregularity and optical properties of resultant polyacetylenes are obviously affected by flexible terminal alkoxy chain length. The cis olefinic structure content in polyacetylene backbone increases with increasing terminal alkoxy group length. The functional polyacetylene with the higher cis olefinic structure content shows higher thermal stability, better optical limiting property and larger third-order nonlinear optical performance. The optical limiting mechanism of resulting polymers was investigated, which is mainly originated from larger excitation state absorption cross-section of molecules to result in reverse saturable absorption.

  • Synthesis, crystal structures, mesomorphic and photo-luminescent properties of 1,3,4-thia(oxa)diazole-based compounds with a terminal methoxy or methylthio group

    A series of aromatically 2,5-disubstituted 1,3,4-thia(oxa)diazoles with a terminal methoxy or methylthio group were synthesized and characterized by means of (1)H NMR, (13)C NMR, MS and elemental analysis. The X-ray crystal structures of compounds 1a and 3b revealed that both of them adopted layered arrangement without short intermolecular interactions. The liquid crystal properties have been investigated by means of polarizing optical microscopy (POM), differential scanning calorimetry (DSC), variable temperature X-ray diffraction (VXRD) and thermogravimetric analysis (TGA). All compounds (except 2a and 2b) exhibited various mesophases (nematic, smectic C and/or smectic A) with wide temperature ranges and good thermal stability. In CH(2)Cl(2) solution, all these compounds displayed a room temperature emission with lambda(max) at 371-425 nm and quantum yields of 0.25-0.83. The effect of the sulfur and oxygen atoms on mesomorphic and photo-luminescent properties was discussed according to the positions in the central heterocyclic rings and the terminal groups.
