Nanoindentation as a probe for mechanically-induced molecular migration in layered organic donor-acceptor complexes

Varughese, S; Mangalampalli, S.R.N. Kiran; Ramamurty, U; Desiraju, G R


Nanoindentation and scratch experiments on 1:1 donor-acceptor complexes, 1 and 2, of 1,2,4,5-tetracyanobenzene with pyrene and phenanthrene, respectively, reveal long-range molecular layer gliding and large interaction anisotropy. Due to the layered arrangements in these crystals, these experiments that apply stress in particular directions result in the breaking of interlayer interactions, thus allowing molecular sheets to glide over one another with ease. Complex 1 has a layered crystal...[Show more]
