T. Fukuda et al., MOLECULAR-ORIENTATION OF POLY(2,2'-BIPYRIDINE-5,5'-DIYL) FILM PREPARED BY VACUUM DEPOSITION ON THE GLASS SUBSTRATE AS DETERMINED WITH SHG TECHNIQUE, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 226, 1993, pp. 207-212
We have found that vacuum-deposited poly(2,2'-bipyridine-5,5'-diyl) PB
Py aligns along glass substrate surface using SHG technique. The SHG a
ctivity originates from the interface where the PBPy molecules coordin
ate to acidic Si-O-H group on the glass surface.
