A rylene-based polychromophore of the general formula I
in which the variables are each defined as follows:
rylene is a radical of the formula
which has been functionalized by at least one imide group, ester group or amide group and which may additionally be substituted by aryloxy, arylthio, hetaryloxy and/or hetarylthio;
X is a rylenedicarboximide radical which absorbs at a different wavelength from the rylene radical, is bonded to the X radical in the peri-position via Y via a moiety
—Y′-A-Y—,
is bonded to the rylene radical and may likewise be substituted by aryloxy, arylthio, hetaryloxy and/or hetarylthio;
A is a bridging member having at least one aromatic or heteroaromatic radical, the Y or Y and Y′ groups being bonded to the aromatic or heteroaromatic radical;
Y is a moiety
Y′ is a moiety
where the moieties (i) and (ii) may be part of the ester groups of the rylene radical and the moieties (iii) are part of the imide groups of the rylene radical and the moieties (iv) are part of the amide groups of the rylene radical;
R
1
is hydrogen or C
1
-C
18
-alkyl, where the R
1
radicals may be the same or different when they occur repeatedly;
n is 1, 2 or 3;
x is from 1 to 7.
基于莱林的多色团的一般公式I,其中变量各自定义如下:莱林是一种具有下述结构的基团,已被至少一个酰亚胺基团、酯基团或酰胺基团官能化,并且还可以被芳氧基、芳硫基、杂芳氧基和/或杂芳硫基取代;X是一种莱林二酰亚胺基团,其在不同波长处吸收于莱林基团,通过Y通过一个团—Y′-A-Y—与X基团在邻位键合,与莱林基团键合,同样可以被芳氧基、芳硫基、杂芳氧基和/或杂芳硫基取代;A是至少具有一个芳香或杂芳基团的桥接成员,Y或Y和Y′基团与芳香或杂芳基团键合;Y是一个团,Y′是一个团,其中团(i)和(ii)可能是莱林基团的酯基团的一部分,团(iii)是莱林基团的酰亚胺基团的一部分,团(iv)是莱林基团的酰胺基团的一部分;R1是氢或C1-C18-烷基,当它们重复出现时,R1基团可能相同也可能不同;n为1、2或3;x为1到7。
