A new synthetic approach towards the preparation of functionalised, soluble, donor–acceptor (DA) alkylbithiophene derivatives of oxadiazole, thiadiazole and triazole is reported. Taking advantage of the Fiesselmann reaction, reactive bithiophene synthons having alkyl or alkoxy substituents at designated positions are prepared. Following a synthetic strategy, featuring the bottom-up approach, sequential structural elements are built, starting from a simple thiophene compound, until the target molecule is obtained, all in good yield. Supplementing the well established methods of oxadiazole and thiadiazole synthesis, efficient ring closure reaction affording a 4H-1,2,4-triazole unit is presented. All target ambipolar compounds display strong photoluminescence with measured quantum yields up to 0.59. Modification of the demonstrated synthetic routes may be exploited for the preparation of longer, specifically functionalised oligothiophenes, coupled to other heteroaromatic cores.

A synthesis for a new 1,2,6-donor-acceptor-substituted chromophoric benzene system is given. This chromophore is incorporated in a bicyclo[2.2.2]octane system to build up model compounds for electro-optical and dielectrical studies. Furthermore a preparative convenient route to derivatives of 1,4-bis(diphenyl)bicyclo[2.2.2]octane is worked out. The structures of the new compounds are proven by spectroscopical means.

The present work includes synthesis of a series of amide derivatives of glyphosate and their characterization. The structure analysis of these new derivatives was done with the help of FTIR and 1H NMR, Further, their herbicidal activity was analyzed on one of the common weeds (Parthenium hysterophorus). Under the influence of amide derivatives of glyphosate it was found that the chlorophyll content (Chlorophyll a, Chlorophyll b and total Chlorophyll content) of the weed was found to lessen than the control. Moreover, these synthesized derivatives are less polar as compared to the parent glyphosate molecule thereby can emphatically reduce the problem of their leaching into the groundwater.
