C60与含有新型二苯并[18]冠-6系链的双丙二酸酯的区域选择性Bingel大环化提供了一种通用的获得反式-1富勒烯双加合物如（±）-1的途径。钾离子与（±）-1的络合作用对碳球的氧化还原性质具有显著影响，这是由于富勒烯表面与冠醚结合的阳离子非常接近，这是由双桥连加强的。
Regioselective Bingel macrocyclization of C60 with a bis-malonate containing a novel dibenzo[18] crown-6 tether provides a versatile access to trans-1 fullerene bis-adducts such as (±)-1. Complexation of a potassium ion by (±)-1 has a pronounced effect on the redox properties of the carbon sphere as a result of the close proximity of the fullerene surface to the crown ether bound cation, which is enforced by the double bridging.
