Thienyl

In the present work, two new organic sensitizers containing 4,5-bis(4-methoxyphenyl)-1H-imidazole (BPI) and Bodipy as an electron donor and a conjugated bridge, respectively, along with different additional linker groups (phenylene for BPI-P and thienyl for BPI-T) incorporated into the bridge to further expand the absorption spectra and improve the solubility were synthesized and applied in DSSCs.

The bond distances and angles of the thienyl and trifluoromethyl hydrate moieties in the structure are in an acceptable range.

In search of other opioids with good analgesic potency and fewer incidence of side effects mainly respiratory depression, a phenyl piperidine derivative fentanyl and thienyl analogue of fentanyl-Sufentanil and many more were discovered and studied.

Among these unnatural base pairs, the order of the efficiency and selectivity of the unnatural base pairing in T7 transcription is v-y > s-y > x-y.In comparison with the freely rotated 6-dimethylamino group of x, the planarity and the electronegative atoms of the 6-heterocycles, thiazolyl in v and thienyl in s,efficiently exclude the pairing with the natural bases, especially T or U, by the electron negative repulsion with the 4-keto group of T or U, as well as the steric clash.

(16) have shown that fulgides containing heterocyclic structure such as furyl, thienyl, and pyrrolyl were excellent candidates for data storage media because of their efficient thermal stability.

where R is selected from [C.sub.1] to [C.sub.6] trial-kyl-silyl groups, [C.sub.1] to [C.sub.20] alkyl groups, [C.sub.4] to [C.sub.20] cycloalkyl groups, [C.sub.6] to [C.sub.20] aryl groups, thienyl, furyl, and pyridyl groups; and R may optionally have attached thereto any of the following functional groups: [C.sub.1] to [C.sub.10] alkyl groups, [C.sub.6] to [C.sub.20] aryl groups, [C.sub.2] to [C.sub.10] alkenyl groups, [C.sub.3] to [C.sub.10] non-terminal alkynyl groups, ethers, tert-amines, oxazolines, thiazolines, phosphines, sulfides, silyls and mixtures thereof; where [R.sup.1] is selected from [C.sub.2] to [C.sub.80] alkylene groups, where X is NR, and where [pi] is a polymer chain.

The in situ formed intermediate thienyl diazonium sulphate 5 (Scheme 2) was generated from the diazotization of compound 4 using nitrosylsulfuric acid at a very low temperature (0-5[degrees]C).
