通过Stille偶联反应和Kumada催化转移缩聚（KCTP）两步法合成了含聚3-己基噻吩（P3 HT）侧链的全共轭接枝共聚物。合成了一系列不同组成的3-萘二酰亚胺共聚物，4′-氯-3 ′-甲苯基）噻吩（CTT）单元（PNDICTT）被设计为n型主链，而聚将3-（4′-氯-3 ′-甲苯基）噻吩-alt-噻吩（PCTT）设计为p型主链，将其转化为n型或p型大分子引发剂，然后在室温下通过外部引发的KCTP从大分子引发剂原位接枝P3 HT侧链。通过使用这种新开发的用于合成全共轭接枝共聚物的两步法，接枝共聚物中的P3 HT侧链的数目可以简单地通过改变PNDICTT中的CTT单元的组成来控制。与此同时，链条…
All-conjugated graft copolymers containing poly(3-hexylthiophene) (P3HT) side chains and both of p-type and n-type backbones that are connected with all π-conjugated linkages were synthesized via a two-step method involving the Stille coupling reaction and Kumada catalyst-transfer polycondensation (KCTP). A series of naphthalene diimide copolymers with different compositions of 3-(4′-chloro-3′-tolyl)thiophene (CTT) units (PNDICTT) were designed as n-type backbones, while the poly(3-(4′-chloro-3′-tolyl)thiophene-alt-thiophene) (PCTT) was designed as a p-type backbone which were converted into n-type or p-type macroinitiators, and P3HT side chains were then in situ grafted from the macroinitiators via an externally initiated KCTP at room temperature. By using this newly developed two-step method for the synthesis of all-conjugated graft copolymers, the number of P3HT side chains in the graft copolymers can be simply controlled by varying the composition of the CTT units in PNDICTT. Meanwhile, the chain leng...
