Substituted phthalocyanines of a formula (I) ##STR1## wherein M is a metal atom or a metal halide or oxide, or M is 2H, one H being bonded to each of the bonding N atoms (29 and 31 positions) shown, R.sub.1 to R.sub.8 are the same or different and are independently selected from C.sub.1 to C.sub.20 alkyl, C.sub.1 -C.sub.20 alkenyl, --X--COO--X.sup.1, --X--O--Y, .alpha., and --X--COZ where X is independently selected from a chemical bond, (--CH.sub.2).sub.n where n=0-20 or (CH.sub.2).sub.n --CH.dbd.CH (--CH.sub.2).sub.b where a and b are independently selected from 0-20 and a+b is in the range 0-20, X.sup.1 is independently selected from C.sub.1 -C.sub.20 alkyl or C.sub.2 -C.sub.20 alkenyl, Y is independently selected from C.sub.1 -C.sub.20 alkyl, C.sub.2 -C.sub.20 alkenyl or H and Z is selected from OH or NR.sup.1 R.sup.11 where R.sup.1 and R.sup.11 are independently selected from H, C.sub.1 -C.sub.20 alkyl and C.sub.2 -C.sub.20 alkenyl, provided that where Y is alkyl and X is a chemical bond at least one of the groups R.sub.1 -R.sub.8 is selected from --X--COO--X.sup.1 and --X--COZ, and further provided that is R.sub.1 -R.sub.8 all contain more than 6 carbon atoms and are all selected from alkyl or --X--O--Y where X is --(CH.sub.2)--.sub.n and Y is alkyl then R.sub.1 -R.sub.8 are not all in the 2, 3, 9, 10, 16, 17, 23 and 24 positions indicated in formula I. These phthalocyanines may exhibit discotic liquid crystal phases, absorb infra-red radiation and make good Langmuir-Blodgett films.
公式(I)的替代酞菁化合物为:##STR1## 其中,M是金属原子或金属卤化物或氧化物,或M是2H,其中一个H与所示的键合N原子(29和31位置)各自键合,R.sub.1到R.sub.8相同或不同,且独立地从C.sub.1到C.sub.20烷基,C.sub.1-C.sub.20烯基,--X--COO--X.sup.1,--X--O--Y,α和--X--COZ中选择,其中X是独立选择的化学键,(--CH.sub.2).sub.n其中n = 0-20或(CH.sub.2).sub.n --CH.dbd.CH (--CH.sub.2).sub.b,其中a和b独立选择于0-20且a+b在0-20范围内,X.sup.1独立选择自C.sub.1-C.sub.20烷基或C.sub.2-C.sub.20烯基,Y独立选择自C.sub.1-C.sub.20烷基,C.sub.2-C.sub.20烯基或H,Z选择自OH或NR.sup.1R.sup.11,其中R.sup.1和R.sup.11独立选择自H,C.sub.1-C.sub.20烷基和C.sub.2-C.sub.20烯基,但是当Y是烷基且X是化学键时,R.sub.1-R.sub.8中至少有一个群被选择自--X--COO--X.sup.1和--X--COZ,而且进一步提供,如果R.sub.1-R.sub.8都含有超过6个碳原子并且全部选择自烷基或--X--O--Y,其中X为--(CH.sub.2)--.sub.n且Y为烷基,则R.sub.1-R.sub.8不全部位于公式I中指示的2、3、9、10、16、17、23和24位置。这些酞菁化合物可能表现出圆盘状液晶相,吸收红外辐射,并制备良好的Langmuir-Blodgett膜。
