Abstract
A process for synthesizing nanostructures is disclosed. The process involves forming a liquid crystalline template by combining a block copolymer, a first reactant in a polar phase, and a nonpolar phase, then contacting the template with a gas phase composed of a second reactant, under conditions effective to form nanostructures.

A process for synthesizing nanostructures, said process comprising:
- providing a first reactant in a polar phase;
- forming a liquid crystalline template containing the first reactant;
- contacting the liquid crystalline template with a gas phase comprising a second reactant diluted in a carrier gas;
- and
- allowing the second reactant to react with the first reactant;
- under conditions effective to form nanostructures.
A process for synthesizing hollow nanostructures, said process comprising:
- combining together 67 wt % zinc acetate dihydrate, 31 wt % poly (ethylene oxide) and poly (propylene oxide), and 2 wt % p-xylene, thereby forming a liquid crystalline template;
- and
- diffusing H2Se gas into said liquid crystalline template;
- wherein zinc acetate dihydrate reacts with H2Se to form hollow ZnSe nanostructures.
A process for synthesizing solid nanostructures, said process comprising:
- combining together 10 wt % zinc acetate dihydrate, 58 wt % poly (ethylene oxide) and poly (propylene oxide), and 32 wt % p-xylene, thereby forming a liquid crystalline template;
- and
- diffusing H2Se gas into said liquid crystalline template;
- wherein zinc acetate dihydrate reacts with H2Se to form solid ZnSe nanostructures.
A liquid crystalline template produced by the process comprising:
- providing a block copolymer;
- providing a nonpolar phase;
- providing a first reactant in a polar phase;
- and
- allowing the block copolymer, non-polar phase, and first reactant in a polar phase to come into contact with each other, such that said polar phase is continuous and said nonpolar phase is dispersed within the continuous phase, under conditions effective to form said liquid crystalline template.
