摘要：

A new dinaphthyridine receptor 1 is designed that efficiently binds to urea probably by six hydrogen bonds forming a chloroform soluble 1:1 complex and selectively extracts urea into chloroform from its mixture with thiourea. The receptor 1 has fifteen fold higher binding constant for urea than the truncated receptor 2 possibly due to formation of greater number of hydrogen bonds in complexation.
