Abstract:
A fluorinated phenanthrene derivative of the formula (1) where the symbols and indices are defined as follows:G1 is â€”H&boxH;CHâ€” or â€”CH2CH2â€”; X1, X2, X3 and X4, independently of one another. are H of F, with the provisos that a) X1, X2, X3, X4 are not simultaneously H b) X1, X2, X3, X4 are not simultaneously F Y1 and Y2, independently of one another, are H or F; R1 and R2 are identical or different and are a) a straight-chain or branched alkyl radical (with or without an asymmetrical carbon atom) having 1 to 20 carbon atoms, in which, in addition, one or more H atoms may be replaced by F and where a1) one At more non-adjacent and non-terminal â€”CH2â€” groups may be replaced by â€”Oâ€”, â€”Sâ€”, â€”COâ€”Oâ€”, â€”Oâ€”COâ€”, â€”Oâ€”COâ€”Oâ€” or â€”Si(CH3)2â€”, and/or a2) one or more â€”CH2â€” groups may be replaced by â€”CH&boxH;CHâ€”, â€”Câ‰¡Câ€”, cyclopropane1,2-diyl, 1,4-phenylene, 1,4-cyclohexylene or 1,3-cyclopentylene, and/or a3) the terminal â€”CH3 group may be replaced by one of the following chiral groups (optically active: or racemic): R1 is alternatively hydrogen, â€”OCF3, â€”CF3, â€”CN, â€”F, â€”Cl, â€”OCHF2, â€”OCH2F, â€”CHF2 or â€”CH2F; b) R1 is alternatively hydrogen, Cl or F; R3, R4, R5, R6 and R7 are identical or different and are a) hydrogen b) a straight-chain or branched alkyl radical (with or without an asymnmetrical carbon atom) having 1 to 16 carbon atoms, where b1) one or more nonadjacent and non-terminal â€”CH2â€” groups may be replaced by; â€”Oâ€”; and/or b2) one or two â€”CH2â€” groups may be replaced by â€”CH&boxH;CHâ€”, c) R4 and R5 together may alternatively be â€”(CH2)4â€” or â€”(CH2)5â€” if they are bonded to an oxirane, dioxolane, tetrahydrofuran, tetrahydropyran, butyrolactone or valerolactone system; with the proviso that R3 can only be hydrogen If R3 is a substituents of one of the ring systems mentioned;M1 is â€”COâ€”Oâ€”, â€”CH2â€”Oâ€”, â€”CH&boxH;CHâ€”, â€”Câ‰¡Câ€”, â€”CH2â€”CH2â€”COâ€”Oâ€”, â€”CH2CH2CH2CH2â€”, â€”CH2CH2CH2Oâ€” and mirror-image arrangements thereof or a single bond; A1 is 1,4-phenylene, in which one or more H atoms may be replaced by F, Cl and/or CN, 1,4-cyclohexylene, in which one or two H atoms may be replaced by CN and/or CH3 arKdor F, naphthalene-2,6-diyl, in which one or more H atoms may be replaced by F, Cl and/or CN; or a single bond.
