Structure-mechanical property correlation of a series of 4-(1-Napthylvinyl) pyridine based cocrystals

We obtained three 4-(1-Napthylvinyl) pyridine based cocrystals ( 1–3 ) and studied its structure mechanical property correlation which aimed towards various applications for photo switches, mechanical actuators etc. Selection of coformer molecules is important in fine tuning mechanical property outcome of synthesized cocrystals. Amongst three cocrystals, cocrystal 1 is mechanically flexible and its mechanical property is attributed to underlying crystal packing features which is in line with existing elastically bendable crystals while other two cocrystals ( 2, 3 ) are brittle in nature. Hirshfeld analysis was carried out to illustrate structure-property correlation particularly in terms of number as well as types of non-covalent interactions in the lattice and further to corroborate the space of the molecules in the lattice.
