摘　　要：The binding behavior of pillar[5]arenes(P5 As)towards a series of olefin guests((E)-1,4-dichlo robut-2-ene(1 E),(Z)-1,4-dichlo robut-2-ene(1 Z),(E)-but-2-ene-1,4-diol(2 E),and(Z)-but-2-ene-1,4-diol(2 Z),as well as an alkyne derivative 1,4-dichlorobut-2-yne(3))have been studied in organic solution.P5 As exhibit considerable selectivities for the trans-olefin isomers(1 E and 2 E)over their cis-isomers(1 Z and 2 Z).The cis/trans-selective interactions hold the potential of utilizing P5 As to separate olefin isomers.
