meta -Terphenyl derivatives were used as versatile fluorescent sensors for online monitoring of hybrid photopolymerization that allow seeing the difference between different types polymerization processes involved in polymerization.

5-pyrrolidino-m-terphenyl (1) is synthesized via a Buchwald-Hartwig cross-coupling reaction. This terphenyl readily halogenated under ambient conditions with tetrabutylammonium tribromide to generate 4-pyrrolidino-2,6-diphenylbromobenzene (2). The reaction of (2) magnesium results in the conversion its corresponding Grignard reagent (3). Quenching (3) water recovery (1), demonstrating ability r...

The development of new methodologies to affect non-ortho-functionalization of arenes has emerged as a globally important arena for research, which is key to both fundamental studies and applied technologies. A range of simple arene feedstocks (namely, biphenyl, meta-terphenyl, para-terphenyl, 1,3,5-triphenylbenzene, and biphenylene) is transformed to hitherto unobtainable multi-iodoarenes via a...

In the meta-terphenyl fragment of the title mol-ecule, C(29)H(22)F(2)O(2), the two fluoro-phenyl rings are twisted from the central benzene ring by 46.72 (6) and 41.70 (6)°, respectively. In the crystal, weak C-H⋯O and C-H⋯F hydrogen bonds link the mol-ecules into layers parallel to the ab plane. The crystal packing exhibits π-π inter-actions, the shortest distance between the centroids of arom...

The title compound, C(29)H(22)F(2)O(3), is a meta-terphenyl derivative featuring a Michael-system-derived substituent with an E-configured C=C function. In the crystal, C-H⋯O and C-H⋯F contacts connect the mol-ecules into planes parallel to (101). The shortest centroid-centroid distance between two aromatic systems is 3.7169 (7) Å and is apparent between the terminal benzene ring of the Michael...

Diverse p-terphenyl compounds, named curtisians, have been isolated from the fungus Paxillus curtisii, and degradation of wood by this fungus is thought to be progressed by iron chelation of p-terphenyl curtisians. In this study, the iron chelation ability of p-terphenyls has been proved by chrome azurol S (CAS) assay, reducing power, and UV-visible spectroscopic analyses. The catechol moiety o...

The conformation of p-terphenyl (C18H14) and deuterated p-terphenyl (C18D14) has been investigated, using high-pressure infrared spectroscopy at liquid-helium temperatures. First-principles calculations, together with the experimental results, were performed to determine the structure of p-terphenyl in the twisted conformation. At low temperatures and pressures, p-terphenyl belongs to the C2 po...

Two novel phenylacetoxylated p-terphenyl derivatives, namely ganbajunin F (6'-methoxy-2'-phenylacetoxy-3', 4, 4", 5'-tetrahydroxy- p-terphenyl), and ganbajunin G (5'-methoxy-2'-phenylacetoxy-3', 4, 4", 6'-tetrahydroxy-p-terphenyl), together with a known compound cycloleucomelone were isolated from the fruiting bodies of Thelephora ganbajun Zang. Their structures were established on the basis of...
