Phthalocyanine of formula (I), wherein M is a metal or is 2H, bonded at 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, a, 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.a CH--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 are independently selected from H, C.sub.1 -C.sub.20 alkyl and C.sub.2 -C.sub.20 alkenyl. These phthalocyanines may exhibit discotic liquid crystal phases, absorb infra-red radiation and make good Langmuir-Blodgett films.
式(I)的邻苯二酸二甲酯,其中M是金属或2H,29和31位点结合,R.sub.1至R.sub.8相同或不同,可独立选择从C.sub.1到C.sub.20的烷基,C.sub.1-C.sub.20的烯基,--X--COO--X.sup.1,--X--O--Y,a和--X--COZ,其中X可独立选择从化学键,(CH.sub.2).sub.n其中n-0-20或(CH.sub.2).sub.aCH--CH(CH.sub.2).sub.b其中a和b可独立选择从0-20且a+b在范围0-20内,X.sup.1可独立选择从C.sub.1-C.sub.20烷基或C.sub.2-C.sub.20烯基,Y可独立选择从C.sub.1-C.sub.20烷基,C.sub.2-C.sub.20烯基或H,Z可从OH或NR.sup.1R.sup.11中选择,其中R.sup.1至R.sup.11可独立选择从H,C.sub.1-C.sub.20烷基和C.sub.2-C.sub.20烯基。这些邻苯二酸二甲酯可能表现出圆盘液晶相,吸收红外辐射并制备出良好的Langmuir-Blodgett膜。
