Abstract

Liquid crystals are highly anisotropic molecular systems which exhibit phase transitions in several stages on going from the crystal to the isotropic liquid phases. Mesophases such as smectic A and nematic phases are defined depending on orientational and spatial ordering of molecules. Effects of molecular anisotropy of the liquid crystal on chemical reactions and photo-physical processes now receive increasing attention [1–4]. It has been shown [5] that in a luminescent liquid crystal, dodecylcyanobiphenyl (12CB), two kinds of fluorescence are emitted in various phases. The dual fluorescence emission was interpreted in terms of singlet monomer and excimer formation.
