Synthesis of 1,3,5-alternate azacalix[3]pyridine[3]pyrimidine and its complexation with fullerenesvia multiple π/π and CH/π interactions†
Abstract
Azacalix[3]pyridine[3]pyrimidine was synthesized efficiently by means of a [3+3] fragment coupling approach. Adopting a preorganized symmetric 1,3,5-alternate conformation, the
