In an article, published in an article, once mentioned the application of 4488-22-6, Name is [1,1′-Binaphthalene]-2,2′-diamine,molecular formula is C20H16N2, is a conventional compound. this article was the specific content is as follows.name: [1,1′-Binaphthalene]-2,2′-diamine
The dipole moment (mu = 2.37 D), refraction (R = 106.71 cm3 ), and molar Kerr constant (mK x 1012 = -97.4) of 2,2′-diamino-1,1′-binaphtyl have been determined in benzene at 25.0 deg and lambda = 6328 Amstroem.The Kerr constant was measured by a relative method on apparatus with a special device for the preparation of solutions.The principal polarisabilities of the molecule (b1 = 36.05, b2 = 40.36, and b3 = 37.64 Amstroem3) shown that the ellipsoid of polarisability is somewhat extended in the direction of the 1,1′-bond.It is show that the naphthalene nuclei in the molecule are rotated about the 1,1′-bond by an angle phi cca 94 deg, i.e. the planes of the naphthalene rings are approximately perpendicular.94 degC, i.e. the planes of the naphthalene rings are approximately perpendicular.
