Abstract
|
|
|
|
| The synthesis of novel upper rim calix[4]arenetetrathiafulvalene conjugates 1ad has been performed by bridging the tetrachloromethylated calix[4]arene derivative 4 with the corresponding tetrathiafulvalene-dithiolates. The cyclic voltammetry of 1ad shows a two-step oxidation behavior, whereas NMR binding titrations showed their binding affinity to pyridinium salts. X-ray structure of 4 features calixarene fixed in the pinched cone conformation; its crystal packing is defined by the network of CH···Cl weak hydrogen bonds. |
