ANTHRACENE DERIVATIVES

摘要

Anthracene Derivatives New compounds useful as sensitizers in photocurable polymer systems have the formula: (I), wherein p is 1 or 2 and q is 0 or 1 provided that p+q is 1 or 2; each R is independently a residue of formula: -A-(Q)k (II), wherein A is a residue of formula (III), wherein n is an integer from 1-17, k is 1 or 2, R5 and R6 are the same or different and each is a straight- or branched chain alkyl group having 1 to 5 carbon atoms and, when Q is COOR2 either R5 or R6 is optionally substituted by a COOR2 group the R2 groups being the same or different, provided that when R5 or R2 is substituted by a COOH group (R2=H) then the compound of formula I does not contain more than three COOH groups or R5 or R6 may be linked to the residue CnH2n+1-k to form a C5-C12 cycloalkylene residue substituted by the group -(CO2R2)k wherein the R2 groups independently, have their previous significance and k has its previous significance; Q is a residue -COZR2 wherein Z is 0 or NR3 and R2 is H, straight- or branched chain alkyl having 1 to 18 carbon atoms, a straight- or branched chain alkenyl group having 3 to 18 carbon atoms, cycloalkyl having 3 to 12 carbon atoms or an aralkyl group having 7 to 9 carbon atoms and, when Z is -NR3, R3 is hydrogen or a straight- or branched chain alkyl group having 1 to 18 carbon atoms, or R2 and R3, together with the nitrogen atom to which they are each bonded, may form a 5- or 6-membered heterocyclic ring; or Q is a residue -OX wherein X is -R3 or -CoR4 wherein R3 is as above and is H, straight- or branched alkyl having 1 to 18 carbon atoms, a straight- or branched chain alkenyl group having 3 to 18 carbon atoms or cycloalkyl having 3 to 8 carbon atoms; a residue CN; each R1, independently, is straight- or branched chain alkyl having 1 to 8 carbon atoms, aralkyl having 7 to 9 carbon atoms optionally substituted by one or two halogen atoms, an alkyl (C1-C4)-cyclo-alkyl(C5-C12) group, or R1 is a residue of formula II and, when R1 is a residue of formula II, then R1 and R may be the same or different; and salts thereof with organic or inorganic bases.
