“…In one published variation on this approach, a 1,2‐double bond is introduced into the cyclisation product by dehydrogenation (Scheme ); acid catalysed rearrangement of the dienone in the presence of acetic anhydride gives a ring A aromatic [10‐ 14 C]steroid 172. A further variation (Scheme ) involves the α‐acylation of the lactone precursor with dilabelled acetyl chloride, and decarboxylative ring closure of the resulting diketoacid to give [3,4‐ 12 C 2 ]estradiol benzoate 174…”

A variety of methods for the preparation of selectively mono-, di-or tri-labelled arenes are reviewed. The review concentrates on those for which the application to labelled synthesis has been demonstrated. Further methods, the application of which to labelled synthesis appears viable but which have not been reduced to practise, are included also. The available methods provide a range of substitution patterns.

“…13 C]estradiol was prepared from 19-nortestosterone (Steraloids, Inc.) using the method reported by [Yuan 1982] C]estradiol) using the aromatization procedure of Rao et al [1994]. The adamantyl [3- C-labeled sterols were embedded in DPPC multi-lamellar vesicles (MLVs) by the following procedure.…”

“…Later, Yuan and Ma explored the size effect of the π‐conjugation in the end group on the molecular packing and corresponding OPV performance. [ 79 ] Incorporation of benzene, naphthalene, or pyrene as end groups to a DPP core led to different degree of crystallinity. GIWAXS patterns indicated that pyrene, as the largest end group, leads to high crystallinity and the highest hole mobility among the three molecules (1–2 orders larger than the other two molecules).…”

Self‐assembly is a bioinspired strategy to craft materials for renewable and clean energy technologies. In plants, the alignment and assembly of the light‐harvesting protein machinery in the green leaf optimize the ability to efficiently convert light from the sun to form chemical bonds. In artificial systems, strategies based on self‐assembly using noncovalent interactions offer the possibility to mimic this functional correlation among molecules to optimize photocatalysis, photovoltaics, and energy storage. One of the long‐term objectives of the field described here as supramolecular energy materials is to learn how to design soft materials containing light‐harvesting assemblies and catalysts to generate fuels and useful chemicals. Supramolecular energy materials also hold great potential in the design of systems for photovoltaics in which intermolecular interactions in self‐assembled structures, for example, in electron donor and acceptor phases, maximize charge transport and avoid exciton recombination. Possible pathways to integrate organic and inorganic structures by templating strategies and electrodeposition to create materials relevant to energy challenges including photoconductors and supercapacitors are also described. The final topic discussed is the synthesis of hybrid perovskites in which organic molecules are used to modify both structure and functions, which may include chemical stability, photovoltaics, and light emission.
