2- anthracenesulfonates

CDx and in particular 7-CDx are known to accommodate two aromatic moieties under certain circumstances. Hence if two appropriate prochiral guest molecules are included in the same CDx cavity, regio- and enantioselective bimolecular photoreactions are expected to occur [108]. Indeed, it is known that the presence of CDx not only accelerates the rate but also modifies the product distribution of photocyclodimerizations of anthracene derivatives [109-111], coumarin derivatives [113-115], stilbene derivatives [116,117], stilbazole [118], and tranilast [119]. For instance, Tamaki and coworkers reported significantly enhanced quantum yields of photodimerization of anthracenesulfonates and anthracenecarboxyl-ates in the presence of 3- and 7-CDx [109-111]. These anthracene derivatives form 2 2 and 2 1 guest-host complexes with (3- and 7-CDx, respectively, and... 

A supramolecular hydrogel underwent a reversible gel-sol transformation that was formed by adding 9,10-dimethoxy-2-anthracenesulfonic acid to an aqueous dispersion of a cationic amphiphile, (I), as was previously prepared by the author [1]. The gel had a network with a bilayer-membrane and a nanofiber...

ABSTRACT. The photodimerization of 2-anthracenesulfonate in water was accelerated in the presence of 3- and y-cyclodextrins (CyDs). While four configurational isomers of the photodimer were obtained in the presence of Y-CyD with similar ratio of the yields to that in the host-free solution, only one of the isomers was obtained in the presence of 3-CyD. The results were explained by the formation of two guest-one host inclusion complex in the former case and of two guest-two host inclusion complex in the latter. No evidence of an inclusion complex with a-CyD was obtained. The inclusion effects of CyD on the photodimerization of other water-soluble anthracenes were also examined. 

The preparation of 1- (IAS) and 2-anthracenesulfonates (2AS) was described elsewhere (16). The preparation of 1- (lAC) and 2-anthracenecarboxylates (2AC) was carried out by the haloform reaction of corresponding acetyl-anthracenes. 9-Anthracenecarboxylate (9AC) was used as commercially available. ...
