摘要: Abstract 1,2-Diaminopropane (1,2-DAP) provides an unusual example of organic co-intercalate where graphite intercalation compounds (GICs) show intra-gallery orientation dependant on the identity alkali metal cation intercalate (Li+, Na+, or K+). The GIC gallery heights, K(1,2-DAP)yCx = 0.697 nm and Li(1,2-DAP)yCx = 0.782 nm, indicate 1,2-DAP long axis orientations that are parallel perpendicular to graphene sheets, respectively.
