文摘

DIBPillar[n]arenes (n = 5, 6) were synthesized. They showed different host−guest properties with n-octyltriethyl ammonium hexafluorophosphate G due to their different cavity sizes. DIBpillar[5]arene showed no complexation with G, while DIBpillar[6]arene formed a 1:1 complex with G with an association constant of 334 (±24) M⁻¹ in chloroform. In this letter, the first pillar[6]arene crystal structure and the first investigation of the host−guest chemistry of pillar[6]arenes are reported.
