چکیده
In the title compound, C(16)H(14)N(2)O(3), the essentially planar 1,3,4-oxadiazole ring [maximum deviation = 0.0021 (11) Å] is inclined at dihedral angles of 8.06 (6) and 11.21 (6)° with respect to the two benzene rings; the dihedral angle between the latter rings is 11.66 (5)°. In the crystal, short inter-molecular C⋯O inter-actions [2.9968 (15) Å] connect adjacent mol-ecules into chains propagating in [203]. The crystal structure is further stabilized by weak inter-molecular C-H⋯π inter-actions.

New Thermally Stable Aromatic Polyimides Based on Aromatic Diamine 2,5-Bis(3-amino-4-methyl benzene)-1,3,4-oxadiazole (BAMO): Synthesis and Characterization
In current study, the synthesis and characterization of novel thermally stable polyimides (PIs) containing an 1,3,4-oxadiazole moiety based on a diamine, i.e. 2,5-bis(3-amino-4-methyl benzene)-1,3,4-oxadiazole (BAMO), have been reported. The polymers were characterized using FT-IR and elemental analysis (CHN). Thermal and mechanical behaviours of the prepared PIs were studied by thermo-gravimet...

In the title compound, [CuCl(2)(C(6)H(7)N)(2)(C(12)H(8)N(4)O)](n), the Cu atom, located on an inversion center, is coordinated by four N atoms from two aniline ligands and two 2,5-bis-(4-pyrid-yl)-1,3,4-oxadiazole ligands. Two Cl atoms lying above and below the plane formed by these four N atoms inter-act weakly with the Cu atom [Cu-Cl = 2.7870 (7) Å]. The trans 2,5-bis-(4-pyrid-yl)-1,3,4-oxadi...

The compound, C(32)H(28)N(4)O(5), which was synthesized by the reaction of 2,5-bis-(2-hydroxy-lphen-yl)-1,3,4-oxadiazole with N-benzyl-2-chloro-acetamide, lies on a twofold rotation axis which passes through the mid-point of the N-N bond and the O atom of the oxadiazole unit. The phenyl-ene and oxadiazole rings are almost coplanar [dihedral angle 1.67 (5)°]. The structure is stabilized by intra...

Poly(1,3,4-oxadiazole-ether) with reactive carboxylic acid pendants was synthesized from solution polymerization via nucleophilic displacement polycondensation among 2,5-bis(4-fluorophenyl)-1,3,4-oxadiazole (BFPOx) and 4,4'-bis(4-hydroxyphenyl) valeric acid (BHPA). Without altering the polymeric segments, benzimidazole modified poly(1,3,4-oxadiazole-ether)s were prepared by varying stoichiometr...
متن کاملShedding light on unusual photophysical properties of bis-cyclometalated iridium(III) complexes containing 2,5-diaryl-1,3,4-oxadiazole-based and acetylacetonate ligands.
A DFT/TDDFT investigation was conducted on a series of cyclometalated iridium(iii) complexes with 2,5-diaryl-1,3,4-oxadiazole (oxd(n)) derivatives to shed light on the effects of the stereoisomeric and steric factors on the photophysical properties. On the basis of the results reported herein, we attempt to explain the experimental observations according to which complexes N,N-trans [Ir(oxd(0))...
