- Silicon-Bridged Bi- and Tridentate Lewis Acidic Host Systems
-
Connecting multiple organic spacer functions via silicon core units leads to various organosilanes that are excellently suited as backbones for poly-Lewis acids (PLAs). Using ethynyl spacer groups, rigid bis- and tris-dioxabenzoborole (BCat)-substituted P

- Silylene-diethynyl-arylene polymers having liquid crystalline properties
-
The present invention provides linear organosilicon polymers including diethynyl-(substituted)arylene units, and a process for their preparation. These novel polymers possess useful properties including electrical conductivity, liquid crystallinity, and/or photoluminescence. These polymers possess good solubility in organic solvents. A preferred example is produced according to the following reaction scheme. STR1 These polymers can be solvent-cast to yield excellent films and can also be pulled into fibers from concentrated solutions. All possess substantial crystallinity as revealed by DSC analysis and observation through a polarizing microscope, and possess liquid crystalline properties.
