Dinaphtho[2,1-b:1′,2′-d]thiophene (DNT) is one of the “dynamic thiahelicenes” that is obtained as a racemate due to its low energy barrier for enantiomerization. Careful evaluation of both the metastable DNT film and the stable films of DNT/p

Noria derivatives with pendant methoxy and adamantyl ester moieties (noria MP -AD n ) were synthesized by the substitution reaction of noria analogues with 12 methoxy groups (noria MP ) and 2-bromoacetyloxy-2-methyladamantane (BMA), and their degrees

To improve proton conduction at elevated temperatures, in situ impregnation of Nafion membranes has been carried out by infusing Noria “waterwheel” supramolecules, containing numerous hydroxyl terminal groups, into the ionic domains of Nafion via

Polysilsesquioxanes (PSQs) containing 4-chloromethylphenyl groups were prepared and used for introducing ethylxanthate groups. The obtained PSQs that contained benzyl xanthate structures (XAPSQs) were employed as macroinitiators for grafting acrylami

Extreme ultraviolet (EUV) lithography systems can in principle provide extremely high resolution (line-and-space patterns with less than 22 nm separation) for fabrication of microelectronic devices. For this purpose, various molecular resist material
