A redox-active ferrocene-based heteroditopic receptor bearing a boronic acid (as a catechol recognition site) and a benzo-18-crown-6-ether unit (as an ammonium ion recognition site) was synthesized. A 1:1 ditopic complex with dopamine was evidenced b

A novel molecular sensor using anthracene bearing two amidopyridines emits blue fluorescence in the presence of succinic acid and green fluorescence in the presence of malonic acid, and its fluorescence intensity increased upon binding. Using this mo

Artificial antenna complexes of metal-coordinated bis(8-hydroxyquinoline)-substituted porphyrin networks that mimic antenna chromophores in plants were organized on titanium dioxide electrodes in photoelectrochemical cells. The generated photocurrent

A dye-sensitized solar cell (DSSC) using an anthraquinone bearing two urea groups (as anion recognition moieties) and two carboxylic acids (as anchor moieties to the ZnO electrode) has been prepared. The DSSC causes color changes and large red-shifts

Cis- and trans-dipyridylcalix[4]pyrroles were synthesized and cis-dipyridylcalix[4]pyrrole formed a supramolecular cage upon dimerization and coordination with Pd(II). The cage molecule recognised suberate selectively by hydrogen bonding to the two c

Tris(4-carboxylphenyl)-mono( N -methylimidazolyl)-substituted Zn porphyrin was synthesized as a precursor for a water-soluble supramolecular porphyrin dimer. The dimer formation was performed in a NaHCO 3 aq solution (pH 8.4) and phosphate buffer sol

Described are the electrochemical and 19 F NMR detection of anions, ion-pairs, and zwitterionic L-phenylalanine with the ferrocene-based hetero-ditopic receptor. A cyclic voltammetric study shows that the receptor induces a positive shift in the ferr

Calixpyrroles and related macrocycles are non-aromatic synthetic anion receptors that have attracted considerable attention in recent years. The unfunctionalized, parent calix[4]pyrrole system, also known as octamethylporphyrinogen, may be prepared i
