Photocyclodimerisation and the emissive properties of 4-<2-(p-substituted phenyl)ethenyl>pyridinium ions (stilbazolium ions) (1) intercalated between clay interlayer have been studied in order to clarify the intercalation and mobility of the ions.A statistical product ratio of homo- and cross-bred cyclodimers was observed in the irradiation of an equimolar co-intercalated mixture of 4-<2-(p-tolyl)ethenyl> (1b) and 4-<2-(p-cyanophenyl)ethenyl>-pyridinium chlorides (1c).In contrast, when 1b and 1c were intercalated separately, the homodimers were formed predominantly, and the cross:homo ratios increased with increasing adsorption.This indicates that the molecular diffusion of stilbazolium ions between clay particles is much slower, as was also shown by a quenching study of the excimer fluorescence of 1b by 1c.
