摘要：

Based on m-terphenyl units, concave benzoic acids 11a and 12a were prepared via the 2,6-diarylbenzoic acid 7a. Bromination of 7a with NBS gave 9, and cyclization of 9 with dithiols 10 led to the bimacrocyclic concave acids 11a and 12a. Their relative acidities were determined by photometric titrations in ethanol, and the three-dimensional structure of 11a was determined by X-ray analysis.
