“…At molecular level, such compounds are likely to exhibit large values of molecular hyperpolarizability (β) and they have to have polarizable electrons (conjugated π system) spread over a large distance (Oudar & Chemla, 1977). We have been previously synthesized pyridinium and quinolinium derivatives to study their non-linear optical properties (Chantrapromma et al, 2005(Chantrapromma et al, , 2006Chantrapromma, Jindawong, Fun, Patil & Karalai, 2007;Jindawong et al, 2005). The single-crystal x-ray structural study of the title compound was undertaken in order to establish the structure and conformation of the various groups.…”
