Ti. Shabatina et al., The electronic absorption spectra and molecular aggregate formation in vacuum deposited films of mesogenic cyanobiphenyls and their solutions, MOLEC CRYST, 366, 2001, pp. 2107-2114
Electronic absorption spectra of mesogenic 4-pentyl-4 ' -cyanobiphenyl (5CB
), 4-octyl-4 ' cyanobiphenyl (8CB) and 4-octyloxy- 4 ' -cyanobiphenyl (8OCB
) films produced by cyanobiphenyl molecular vapor deposition were measured.
The appearance of the spectral changes during annealing and dissolution of
cyanobiphenyl film samples are discussed assuming molecular dimerization a
nd H-aggregate formation.
