Metalloporphyrins receptor

Metalloporphyrin receptors (e.g., 73) based solely on a single metal ion-anion coordinative interaction have seen considerable application as receptor species for incorporation in electrode systems (176-180). The main goal in... [Pg.42]

Finally, examples of the third type of ditopic receptor 30, containing two electron deficient metalloporphyrin receptor sites, can be synthesised by the route outlined in Scheme 4 [34]. The properties of these face-to-face porphyrins 39 as selective hosts have not yet been investigated although rather different face-to-face porphyrins have been investigated by Collmann and coworkers in a different context [35]. The diaryIpophyrin system of 39 was selected to provide a well defined structural unit and it is hoped that this approach to a largely pre-or-ganised cavity will prove to be effective. [Pg.224]

The self-assembling principle has begun to be exploited by chemists in the design of synthetic molecular receptors. Hunter and co-workers [61] describe the use of metalloporphyrin coordination chemistry to build up the self-association of a very stable cyclic porphyrin dimer 45 which recognizes derivatives of terephthalic acid (46, 47) through hydrogen-bonding interactions (Scheme 15). [Pg.932]

Receptor 33 also incorporates a secondary Lewis acid anion binding site. This molecule is the zinc metallated ansdogue of 17 with the cobal-tocenium reporter groups replaced with ferrocenes [27]. The freebase precursor to 33 in dichloromethane solution shows no significant anion induced shifts in the H NMR signals of the amide protons, whereas the metalloporphyrin binds bromide (JC = 6200M ), nitrate (K = 2300M i)... [Pg.54]
