WebBackground: Tagetes species produce thiophenes, polyacetylenic compounds that possess strong biocidal activity, thus making Tagetes plants very useful for suppressing nematode populations in the soil and as sources of natural pesticides. In the present study, Tagetes species (T. erecta, T. filifolia, T. lucida, T. minuta, T. patula and T. tenuifolia) grown in … WebOne of them proved to be a monothiophene, the other a methylated bithienyl. The position of these thiophenes in the biosynthetic route was clarified by studying their conversion by Tagetes tissues. After formation of the monothiophene, the pathway branches. One branch leads to the major bithienyls in these species whereas the end product of the ...

WebBis(bithienyl)-1,2-dicyanoethene (4TCE) is a photoswitch that operates via reversible E / Z photoisomerization following absorption of visible light. cis -to- trans photoisomerization of 4TCE requires excitation below 470 nm, is relatively inefficient (quantum yield 5%) and occurs via the lowest-lying triplet.We present excitation-wavelength dependent (565–420 … WebSep 1, 2011 · P3, with a head-to-head bithienyl unit, shows a broader absorption and a lower band gap with respect to P1 and P2, which have tail-to-tail bithienyl units. The PL intensity of P1 – P3 is dramatically quenched in the presence of PCBM, demonstrating that an efficient charge transfer between donor and acceptor occurs. cidco office aurangabad
