Abstract
A method of synthesizing peripherally asymmetric aryl polyhedral oligomeric silsesquioxane (ArPOSS) compounds. The method comprises: wherein Ph is phenyl and wherein R is 1-napthyl, 2-naphthyl, 9-anthracenyl, 9-phenanthrenyl, 1-pryenyl, and mixtures thereof.
Claims16
A method of synthesizing a peripherally asymmetric aryl polyhedral oligomeric silsesquioxane (ArPOSS) compound having a structure:
- wherein Ph is phenyl and wherein R is selected from the group consisting of 1-Naphthyl, 2-Naphthyl, 9-Anthracenyl, 9-Phenanthrenyl, and 1-Pyrenyl, the method comprising:
- reacting an uncondensed phenyl POSS with a trichlorosilane via a capping reaction, the uncondensed phenyl POSS having a structure:
A method of improving solubility of a functionalized polyhedral oligomeric silsesquioxane compound, the method comprising:
- corner-capping an uncondensed phenyl polyhedral oligomeric silsesquioxane with a chlorosilane having a terminal aryl group or a chlorosilane having a polycyclic aromatic functional group.
A method of synthesizing a peripherally asymmetric aryl polyhedral oligomeric silsesquioxane (ArPOSS) compound, the method comprising:
- corner-capping an uncondensed phenyl-POSS alcohol using a chlorosilane having a terminal aryl group or a chlorosilane having a polycyclic aromatic functional group, the terminal aryl group or the polycyclic aromatic functional group being geometrically larger than the phenyl groups of the phenyl-POSS alcohol.
A method of synthesizing a peripherally asymmetric aryl polyhedral oligomeric silsesquioxane (ArPOSS) compound having a structure:
- wherein Ph is phenyl and wherein R is a terminal aryl group that is geometrically larger than phenyl, the method comprising:
- reacting an uncondensed phenyl POSS alcohol with a trichlorosilane via a capping reaction.
