Abstract

Abstract : A robust architecture of C–I⋯π halogen bonds enabled cocrystallisation of azulene as a functional component in the design of pleochroic behavior. Abstract : We describe the rational development of a design for pleochroic molecular solids, by using C−I⋯π halogen bonds to pre-organise different chromophores in a cocrystal. Using the structure of a known naphthalene cocrystal as a blueprint, we demonstrate how a highly robust C−I⋯π motif permits the systematic exchange of original cocrystal components with azobenzene and azulene, resulting in optically interesting dichroic or pleochroic materials.
