The article was written by Martin, Ian J.; Shih, Kuo-Chih; Nieh, Mu-Ping; Kasi, Rajeswari M.. The article contains the following contents:
We report a detailed synthesis and characterization of novel polymeric supramol. structures composed of semiconducting perylene diimide (PDI)-imidazole templates of varying methylene spacer length (n = 3, 4, and 6) hydrogen-bonded to a conjugated polymer backbone of acid-functionalized polydiacetylene (PDA), 10,12 pentacosadiynoic acid. First, a combination of mol. and morphol. characterization tools confirmed that the templated supramol. structures are a result of the synergistic effect of intermol. PDI π-π stacking coupled with noncovalent imidazole-acid interactions. Second, a simple and scalable solid-state polymerization of the drop-cast films by UV radiation delivers multichromic, multiresponsive films capable of unique phase/morphol.-switching properties with a high degree of local ordering. Thermal studies by differential scanning calorimetry and morphol. studies by wide- and small-angle X-ray scattering (WAXS/SAXS, resp.) show dramatic morphol. effects and trends in crystallinity with methylene spacer group extension. Furthermore, UV-vis studies displayed an unusual PDA “”purple phase”” transition, which was addnl. verified by SAXS as a coexistence of previously known red- and blue-phase PDA. Finally, the polymerized drop-cast films displayed reversible thermo- and solvatochromic responses after a second treatment of UV radiation and addnl. UV-thermal cycling revealed the extent of reversibility. The results came from multiple reactions, including the reaction of 6-Aminohexan-1-ol(cas: 4048-33-3Related Products of 4048-33-3)
6-Aminohexan-1-ol(cas: 4048-33-3) can undergo cyclization over copper supported on γ-alumina and magnesia to form hexahydro-1H-azepine. It may be used along with glutaric acid to generate poly(ester amide)s with excellent film- and fiber forming properties.Related Products of 4048-33-3
