Aggregate Structure, Based On Several Multi-dimensional Self-assembly Of The Aromatic Molecules

Several self-assembled aggregates of multidimensional aromatic molecule have beendesigned and synthesized in this thesis. The synthesis of two perylene diimide dyes and theirπ-π interactions, the synthesis and research of several kinds of self-assembled electron"donor-acceptor" supermoleculers of [60]fullerene @ β-CD-perylene diimide dyes/porph-yrin were researched. Four chapters were included in present thesis.The research of self-assembly of multidimensional aromatic molecule was reviewed inChapter 1. The supermolecular structures based on pristine [60]fullerene were prepared withself-assembly technique is the novel innovation.Two soluble substituted perylene diimide dyes, 1,7-Bis(N-pyrrolidinyl)-N,N′-dicyclohexyl perylene-3,4,9,10-tetracarboxylic diimide and 1,7-Bis(p-tert-butylphenoxy)-N,N′-Dicyclohexyl perylene-3,4,9,10-tetracarboxylic diimide was synthesized in Chapter2. The packing behavior of them and the mixture were investigated with photophysicalspectra and structural characterization in solution and in solid state. The additionalelectron donor-acceptor interactions afford strengthened π-π stacking interaction betweenthem.Five self-assembled aggregates of electron "donor-acceptor" system based on "[60]fullerene @ β-CD-perylene diimide dyes/porphyrin" were synthesized in Chapter 3. Thesamples were characterized by IR spectrum and TEM.Six self-assembled aggregates of [60]fullerene @ β-CD-perylene diimide dyes/porphyrin supermolecules constructed by hydrogen bonds bettwen 1,6,7,12-tetra (p-tert-butylphenoxy)-N,N′-dicyclohexyl perylene-3,4,9,10-tetracarboxylic dianhydride andamine were prepared in different solvents in Chapter 4. The samples were characterized byuv-vis spectra and TEM.
