Abstract
  • A new supramolecular crystal engineering approach toward quadratic nonlinear optics isinferred from an acentric cocrystalline template made of two different bi-dimensionaloctupolar molecules: trinitrobenzene (TNB) and triphenylene (TP). The resulting 2-Doctupolar cocrystalline lattice is proposed as a generic template toward multipolar crystallineengineering studies. X-ray diffraction data evidence parallel stacks with alternating verticallyoverlapping TNB and TP units, leading to a significant π−π intermolecular charge transferwhich cannot be accounted for by an oriented gas model.
