Combining a strong donor, tris(dodecyloxy)phenyl)-dithieno[3,2-b:2',3'-d]pyrrole, with a strong acceptor, 4,8-dithien-2-yl-2lambda(4)delta(2)-benzo[1,2-c;4,5-c']bis[1,2,5]thiadiazole, has yielded the lowest bandgap, soluble, spray-processable polymer to date. The polymer has access to four different redox states and shows ambipolar behavior in OFETs. Multiple techniques, including transmission/...
In this work, we studied the processes of vinyl ester formation by addition benzoic acid to phenylacetylene in presence complex catalysts diacetate-di (2-amino-5-methylthio-1,3,4-thiadiazolo) cobalt(II) ([Co(C3H5N3S2)2(CH3COO)2] and tetrakis(2-amino-5-ethylthio-1,3,4-thiadiazole)-zinc(II) dinitrate ([Zn(C4H7S2)4](NO3)2): 1-phenylvinyl benzoate anti-Markovnikov coupling product - styryl were obt...
5-(3-Chlorophenyl)-1,3,4-thiadiazol-2-amine 2 was synthesized and employed to synthesize new 1,3,4-thiadiazole 1,3,4-thiadiazolo[3,2-a]pyrimidine derivatives via reactions with variant electrophilic reagents under solvent-free conditions. The chemical structures of these novel compounds were elucidated scrupulously by aiding elemental data spectroscopic techniques. evaluated for the insecticida...
