A metallic composite in which a conjugated compound having a molecular weight of 200 or more is adsorbed to a metallic nanostructure having an aspect ratio of 1.5 or more, for example, a metallic composite in which a compound having a group represented by the formula (I):
wherein Ar1 is an optionally substituted (n1+1) valent aromatic group; R1 is a direct bond or an (m1+1) valent group; X1 is a hetero atom-containing group; m1 and n1, which are the same as or different from each other, are an integer of 1 or more; when R1, X1 and m1 are plurally present, they each may be the same as or different from each other,
or a repeating unit represented by the formula (II):
wherein Ar2 is an optionally substituted (n2+2) valent aromatic group; R2 is a direct bond or an (m2+1) valent group; X2 is a hetero atom-containing group; m2 and n2, which are the same as or different from each other, are an integer of 1 or more; when R2, X2 and m2 are plurally present, they each may be the same as or different from each other, or both of them is adsorbed to a metallic nanostructure having an aspect ratio of 1.5 or more, is useful for electronic devices such as a light-emitting device, a solar cell and an organic transistor.
一种金属复合材料,其中分子量大于或等于 200 的共轭化合物被吸附在长宽比大于或等于 1.5 的金属纳米结构上,例如,一种金属复合材料,其中具有式 (I) 所代表基团的化合物:
其中 Ar1 是任选取代的(n1+1)价芳香基团;R1 是直接键或(m1+1)价基团;X1 是含杂原子的基团;m1 和 n1 彼此相同或不同,都是 1 或以上的整数;当 R1、X1 和 m1 复数存在时,它们可以彼此相同或不同、
或式 (II) 所代表的重复单元:
其中 Ar2 是任选取代的 (n2+2) 价芳香基团;R2 是直接键或 (m2+1) 价基团;X2 是含杂原子的基团;m2 和 n2 彼此相同或不同,是 1 或更大的整数;当 R2、X2 和 m2 复数存在时,它们可以彼此相同或不同,或者它们都被吸附到长宽比为 1.5或更大时,可用于电子设备,如发光设备、太阳能电池和有机晶体管。
