The team led by academician Huang Wei and Professor Xie Linghai from the institute of information materials and nanotechnology of our university has made a major breakthrough in the field of organic nano-polymers. The research result of stereoskinetic gridization and polygridization with centrosymmetric molecular packing was published online on April 9 in the international top journal Nature Communications. As for the paper, Professor Xie Linghai and academician Huang Wei are corresponding authors, while Lin Dongqing, a doctoral candidate, and Dr. Wei Ying, a young teacher, are co-first authors of the paper.
In this study, the A2B2 type synthesator designed by the team not only overcomes the cross-linking problem, but effectively takes the structural regularity of the nano-polymer under control. Starting from the theory of ‘molecular absorption investing synergy theory (SMART)’, the team came up with the antiparallel and center symmetry molecular arrangement mode by making use of the electronic receptors to PI between attractiveness and protonation of nitrogen impurity fluorene super charge repulsion of electrophilic body, thus conquering the interference of friedel-crafts reaction of thermodynamic equilibrium, so as to realize the implementation the grid and grid meso selectivity of the reaction. Due to the corresponding relationship between A1B1 synthon dimerization of lattice formed by missing Angle and 1948 Dutch master prints the Ritz, Nai, Escher creation “hand to hand painting”, the research team finally named this kind of organic nanoparticles repeat unit as Drawing Hands -type Gridarene (DHG), whose definition also expressed the inter-cultural nano-connection, expecting it to be a chemical way for effective nano-connection.
