On November 30, 2015, Hassan, Kamrul; Yamashita, Ken-ichi; Hirabayashi, Kazunori; Shimizu, Toshio; Nakabayashi, Kazuki; Imai, Yoshitane; Matsumoto, Takashi; Yamano, Akihito; Sugiura, Ken-ichi published an article.Product Details of 14602-86-9 The title of the article was π-Expanded axially chiral biaryls and their emissions: molecular design, syntheses, optical resolution, absolute configuration, and circularly polarized luminescence of 1,1′-bipyrene-2,2′-diols. And the article contained the following:
Axially chiral biaryls based on pyrene, 1,1′-bipyrene-2,2′-diol derivatives, were designed and synthesized from 2-hydroxypyrene. Simple optical resolution was carried out and the absolute configuration was determined by diffraction study. Title compounds (I) and corresponding menthylcarbonate (II) showed clear circularly polarized luminescence (CPL) spectra. The degree of dimensionless Kuhn’s anisotropy in the photoexcited state (|gem|) of compounds I and II were ca. 3.6 x 10-4 and ca. 1.2 x 10-3, resp. High fluorescent quantum yields of compounds I and II, 0.57 and 0.80, resp., in marked contrast to that of BINOL, 0.04 and bathochromic shifts of λCPL were noteworthy properties. The experimental process involved the reaction of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate(cas: 14602-86-9).Product Details of 14602-86-9
