Photoalignment layers for liquid crystals from the di-π-methane rearrangement
Cox, Jason R.,Simpson, Jeffrey H.,Swager, Timothy M.
, p. 640 - 643 (2013)
Photoalignment of nematic liquid crystals is demonstrated using a di-π-methane rearrangement of a designed polymer. The alignment mechanism makes use of the strong coupling of the liquid crystal directors to dibenzobarrelene groups. The large structural c

New multi-electrochromic systems have been developed through the combination of a diaryl ketyl radical system with isophthalate-based electrochromic materials. The location of the isophthalate group in compounds is very critical to obtaining different colors in the multi-electrochromism.

supporting information; experimental part, p. 3258 - 3262 (2010/05/02)
Two novel C60 fullerene derivatives containing one or two perfluorooctyl groups were designed and efficiently synthesized. Organic field-effect transistors based on the bisperfluorooctyl compound 1 show high mobility up to 6.7 × 10-2 cm2 V-1 s and high on/off ratio up to 5 × 107, which qualifies compound 1 as promising n-type conductor material.

Superactivity and dual reactivity of the system N-iodosuccinimide-H 2SO4 in the iodination of deactivated arenes
Chaikovskii,Filimonov,Skorokhodov,Ogorodnikov
, p. 1278 - 1281 (2008/03/27)
Dissolution of N-iodosuccinimide in sulfuric acid gives rise to electrophilic iodine-containing species which are capable of successfully iodinating aromatic compounds with electron-withdrawing substituents in the temperature range from 0 to 20°C. The iodination in sulfuric acid is effected by both protonated N-iodosuccinimide and IOS(O)(OH+)OH intermediate.
Oxidative iodination of deactivated arenes in concentrated sulfuric acid with I2/NaIO4 and KI/NaIO4 iodinating systems
Kraszkiewicz, Lukasz,Sosnowski, Maciej,Skulski, Lech
, p. 1195 - 1199 (2007/10/03)
Deactivated arenes were mono- or diiodinated with strong electrophilic I+ reagents, which were prepared from NaIO4 and either I2 or KI in concentrated H2SO4 (minimum 95% by weight). In general a small excess of the dark brown iodinating solution was used (1.1/1.5 equivalents, for nitrobenzene two equivalents was required). The iodinations were conducted at 25-30 °C with a reaction time of 1-2 hours using either a 'direct' or an 'inverse' method of aromatic iodination to give mono- or diiodinated pure products in 31-91% optimized yields.

Eco-friendly oxidative iodination of various arenes with sodium percarbonate as the oxidant http://www.mdpi.org
Zielinska, Agnieszka,Skulski, Lech
, p. 1307 - 1317 (2007/10/03)
Six easy laboratory procedures are presented for the oxidative iodination of various aromatics, mostly arenes, with either molecular iodine or potassium iodide (used as the sources of iodinating species, I+ or I 3+), in the presence of sodium percarbonate (SPC), a stable, cheap, easy to handle, and eco-friendly commercial oxidant.
Eco-friendly Oxidative Iodination of Various Arenes with a Urea-Hydrogen Peroxide Adduct (UHP) as the Oxidant
Lulinski, Piotr,Kryska, Anna,Sosnowski, Maciej,Skulski, Lech
, p. 441 - 445 (2007/10/03)
Three easy eco-friendly laboratory procedures are presented for the oxidative iodination of various activated and deactivated arenes with molecular iodine, in the presence of UHP (percarbamide), a stable, strongly H-bonded, solid urea-hydrogen peroxide adduct as the oxidant.
Chemical Manganese Dioxide (CMD): Its application to the oxidative iodination of benzene, halobenzenes and some deactivated arenes
Lulinski, Piotr,Krassowska-Swiebocka, Barbara,Skulski, Lech
, p. 595 - 601 (2007/10/03)
After comparing our previous and newer results for numerous oxidative aromatic iodination experiments using various brands (of active MnO2 as the oxidants, we recommend the use of a Chemical Manganese Dioxide (Aldrich CMD; 90+% (MnO2) as the oxidant of choice, since it is satisfactorily pure and chemically active, and is notably less costly than other options.
