A cationic amphiphile for facilitating transport of a biologically active molecule into a cell has the structure A-F-D, in which A is a lipid anchor, D is a head group, and F is a spacer group having the structure described herein. A method for facilitating transport of a biologically active molecule into a cell comprises preparing a lipid mixture comprising a cationic amphiphile having structure A-F-D, preparing a lipoplex by contacting the lipid mixture with a biologically active molecule; and contacting the lipoplex with a cell, thereby facilitating transport of the biologically active molecule into the cell.
