trans-3-(4'-Pyridyl)acrylic acid (4-PA) is inert to photodimerization reaction both in solution and solid state. It is made photoreactive by forming salts with various acids. The anions of these salts play a key role in directing the packing of 4-PAH(+) in the solid state. The anions CF(3)CO(2)(-),

The photodimerization of 2-naphthalenecarbonitrile (2-NpCN) in a cucurbit[8]uril (CB[8]) aqueous solution was investigated. Spectroscopic analysis and product distribution reveal that the use of CB[8] as a host inverted the product selectivity from photodimers 2 and 3 in cyclohexane to photodimer 1

… The agglomeration–fusion ability of the vesicle was endowed probably by the intervesicular interaction between the coumarin group and the fullerene core, as judged by the lack of such ability for the vesicles bearing only alkyl groups and by complete inhibition by conversion of the coumarin group into a photodimer. …
