Keeping this in view, we have designed three new D-A type conjugated polymers carrying 1,3,4-oxadiazole as an electron acceptor moiety and thiophenes with different substitution as electron donors in the polymer backbone with the hope that resulting molecules would show better NLO properties.

A comparable literature exists for polyaniline blends and to a lesser extent blends containing poly(thiophenes) and other conducting polymers.
The whole exercise discovered molecules like thiophenes, benzene, and toluene indicating the presence of hydrogen and carbon, with the latter existing in concentrations higher than 10 parts per million.
Thiophenes, benzothiophene and their alkyl derivatives are present in the GC-SCD chromatogram.
Conducting polymers (CPs) are suitable matrixes for the entrapment of enzymes [30], and they are promising candidates for the enzyme electrode component because they are readily synthesized in the form of thin films by electrochemical polymerization of heterocyclic compounds such as pyrroles and thiophenes [31-33].
In each class of materials, the aromatic moieties may be either benzene derivatives or heteroaromatics such as thiophenes, pyridines, pyrroles and thiazoles.
In this respect, the antimicrobial activities of numerous classes of organic substances such as phenols [1-3], coumarins [4-6], thiophenes [7-9], quinones [10,11], and azo compounds [12-14] are currently the targets of the worldwide drug discovery efforts.
