Three different molecular tweezers containing bis-thiourea groups were efficiently synthesized by a series of organic reactions using anthracene as raw materials. Their structures were confirmed and characterized by melting point, 1H NMR, 13C NMR and HRMS. The recognition behavior of molecular tweezers to several neutral molecules in non-polar environment was studied in detail by fluorescence spectroscopy. The results show that the molecular tweezer 9,10-bis- trifluoromethylphenyl-thioureamethyl anthracene (T-3) has good recognition ability for several guest molecules, and the synergistic effect between the hydrogen bonding and multiple C—H…π interactions on molecular recognition was discussed.

Key words: bis-thiourea tweezer, synthesis, recognition, neutral molecule
