Triphenylamine-based new chemosensors 1 and 2 have been designed and synthesized for fluorometric detection of anions. The urea-amide conjugates in 1 and 2 are involved in binding of anions via hydrogen bonding. UV–vis and fluorescence titration experiments revealed that the sensor 1 has the selectivity for acetate (AcO−), dihydrogenphosphate (H2PO4−) and fluoride (F−) over the other anions examined in the

derivatives featuring anthraquinone as an interior core and terminal electroactive triphenylamine or carbazole groups were prepared by the condensation of 2,6‐dihydroxyanthraquinone with 4‐(diphenylamino)benzoyl chloride and 4‐(9H‐carbazol‐9‐yl)benzoyl chloride, respectively. The electrochemistry and electropolymerization of these monomers were investigated. The polymeric films were built onto ITO/glass

Photoinduced multiple electron-transfer processes of a newly synthesized rotaxane with one acceptor and two donors are studied with the time-resolved fluorescence and absorption methods. In this rotaxane, zincporphyrin (ZnP) with a crown-ether necklace is employed as a photosensitized electron donor; through the crown-ether, a short axle with C60 and triphenylamine (TPA) at both terminals is penetrating
