| titleOfInvention | Photochromic liquid crystal spirobenzopyran compounds, composition comprising the same, photochromic thin films prepared therefrom and method for preparing said compound |
| abstract | The present invention relates to a spirobenzopyran liquid crystal monomer represented by the general formula (1), a composition comprising the same, a thin film prepared using the compound and a method for preparing the compound:n n n (One)n n n Wheren n n R 1 is hydrogen atom or alkyl having 1-22 carbon atoms, or substituted with hydrogen atom, halogen group, hydroxy group, glycidoxy group, amine group, vinyl group, epoxy group, methacryl group, acryl group, amino group or mercto group Alkyl of -22, alkenyl of 1-22 carbon atoms, alkoxy of 1-22 carbon atoms, substituted or unsubstituted phenyl or phenylalkyl;n n n R 2 is a hydrogen atom, a halogen group, a cyano group, a carboxy group, a substituted amino group, a nitro group, an alkyl having 1 to 10 carbon atoms, an alkoxy having 1 to 10 carbon atoms, an alkyl carboxy group having 1 to 10 carbon atoms, a phenyl group or R 1 , respectively. Represents a phenyl group;n n n -X- is -CO-, -CO 2- , -S-, -SO 2- , -C C-, -O-, -C (R 1 ) 2- , -C (R 1 ) = C (R 1 )-, -N = N- or -NR 1- ;n n n Y is the same as X or (CH 2 ) n,-[-C (R 1 ) (R 2 )-] n -,-[-XC (R 2 ) 2 -C (R 1 ) 2- ] n- Either substituent or two or more substituents;n n n m is a number from 1 to 10; In additionn n n n is a number from 0 to 20.n n n The liquid crystal compound according to the present invention has excellent thermal stability, excellent photochromicity, and has self-assembly, from which a photochromic thin film is provided. The compounds according to the invention and compositions containing these compounds are useful in a wide range of applications utilizing photochromic properties and include rewritable membranes, optical switches, photochromic filters, light stabilizers, anti-counterfeiting notes or cards, display elements, thermal It is also useful for use in printers, holograms, three-dimensional recording and display media, and optical integrated devices. |
