摘要:
Liquid-crystalline materials having a cholesteric phase with a pitch of less than 400 nm, comprising a) liquid-crystalline organosiloxanes containing dianhydrohexitol derivatives as chiral groups, and b) chiral monomeric additives which induce the same helicality as the respective liquid-crystalline organo-siloxanes.
摘要:
The invention relates to a method for hydrolyzing hydrolyzable metallic salts, the metallic salts being reacted with emulsions of a) water and b) an inert liquid.
摘要:
The liquid-crystalline organosiloxanes which contain dianhydrohexitol derivatives as chiral groups can be used in optical elements, for decorative purposes and as polarizing colored filters, in particular notch filters.
