A new dinaphthyridine receptor 1 is designed that efficiently binds to urea probably by six hydrogen bonds forming a chloroform soluble I: I complex and selectively extract~ urea into chloroform from its mixture with thiourea. The receptor I has fifteen fold higher binding constant for urea than the
A porphyrin with two appended benzo-crown ethers in the form of a porphyrin-based molecular hveezer was synthesised and shown to bind the bipyridinium guests paraquat. diquat and Pt(bpy)(NH& dications in several solvents. The conformations of the host molecule were shown to be solvent dependent. Lac
