Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 693-67-4, is researched, SMILESS is CCCCCCCCCCCBr, Molecular C11H23BrJournal, Materials Letters called A selectable approach for polarity-fixed and polarity-controllable polymer films with hexagonal columnar structures, Author is Ohno, Takaya; Nonoshita, Sho; Akiyama, Azumi; Kohri, Michinari; Taniguchi, Tatsuo; Kishikawa, Keiki, the main research direction is polarity controllable polymer film hexagonal columnar structure; column polymerized aligned parallel applied elec field LC.Related Products of 693-67-4.
Electroresponsive columnar liquid crystalline urea compounds, N,N’-bis(3,4,5-trialkyloxyphenyl)ureas I and II (1 and 2, resp. ) possessing six and four terminal double bonds, were photopolymerized by UV irradiation in the liquid crystal phases to give polymerized compounds, labeled P-1-Colh and P-2-Colh, that possessed a hexagonal columnar structure. Furthermore, the photo polymerization of 1 and 2 sandwiched between two indium tin oxide-deposited glass plates with applying an elec. field (20 V μm-1), produced polymerized compounds, P-1-Colh-E and P-2-Colh-E, and polarized light optical microscopy clarified that the columns polymerized were aligned in parallel to the applied elec. field. In addition, by the phenomenon that polar substances absorb laser light (λ = 1064 nm) and emit second harmonic generation light (λ = 532 nm), the difference in electro-response between P-1-Colh-E and P-2-Colh-E has been revealed. The former was a polymer whose macropolarity was completely fixed, and the latter was a polymer whose macropolarity was controllable by applying an external voltage.
