Photoreaction of 3,4-Diphenyl-1,2,5-oxadiazole

5,5′-Diphenyl-2,2′-[butane-1,4-diylbis(sulfanedi­yl)]bis­(1,3,4-oxadiazole)

The complete mol-ecule of the title compound, C(20)H(18)N(4)O(2)S(2), is generated by crystallographic inversion symmetry. The benzene ring is almost coplanar with the oxadiazole ring [dihedral angle = 7.2 (2)°].

Preparation and characterization of vapour deposited films based on 2,5-diphenyl-1,3,4-oxadiazole

Synthesis and evaluation of substituted diphenyl-1,3,4-oxadiazole derivatives for central nervous system depressant activity

BACKGROUND Substituted 1,3,4-oxadiazoles are of considerable pharmaceutical interest. 2,5-Substituted diphenyl-1,3,4-oxadiazoles are associated with diverse biological activities by the virtue of -N = C-O- grouping. In the view of wide range of biological properties associated with 1,3,4-oxadiazole, we have synthesized substituted derivatives of 1,3,4-oxadiazole (XIII-XXII), a versatile hydroph...

Electrogenerated chemiluminescence. VIII. Thianthrene-2,5-diphenyl- 1,3,4-oxadiazole system. Mixed energy-sufficient system

Electrogenerated chemiluminescence (ecl) resulting from reaction of the thianthrene (TH) cation radical and the 2,5-diphenyl-l,3,4-oxadiazole (PPD) anion radical in acetonitrile solutions is characterized by emission at wavelengths of both TH and PPD fluorescence. A consideration of the enthalpy of the reaction shows the process to be energy sufficient with respect to formation of excited singl...

Liquid-crystalline heterodimesogens and ABA-heterotrimesogens comprising a bent 3,5-diphenyl-1,2,4-oxadiazole central unit

Three new types of terminally connected ABA-heterotrimesogens and heterodimesogens, composed of a bent 3,5-diphenyl-1,2,4-oxadiazole central unit and one or two rod-shaped 4-cyanobiphenyl cores or one 2-phenyl-1,3,4-thiadiazole core, connected by flexible spacers, have been synthesized, and their mesomorphic behavior was studied by optical polarizing microscopy (PM), differential scanning calor...
