  Contrasting Effect of Alkylation on the Ordering Structure in Isomeric Naphthodithiophene-Based Polymers

  摘要：

  Semiconducting polymers with alkylated naphtho[1,2-b:5,6-b']dithiophene (NDT3) and naphtho[2,1-b:6,5-b']dithiophene (NDT4) are synthesized and characterized. The solubility of the present polymers is significantly improved as compared to the nonalkylated counterparts with preserving the good charge transport properties. Interestingly, the effect of alkylation is found to be quite distinct between the NDT3 and NDT4 cores. In the NDT3-based polymers, alkylation leads to the more ordered backbone structure and thus the increased crystalline order in the thin film. On the other hand, in the NDT4-based polymers, alkylation is detriment to the backbone ordering, which gives rise to the face-on orientation or amorphous like film structure. This difference can be qualitatively explained by the different alkyl placement; all the neighboring alkyl groups are in the anti arrangement in the NDT3-based polymers, whereas the arrangement is a mixture of anti and syn in the NDT4-based polymers, which likely causes steric impact on the backbone. These observations make us better understood how the alkylation affect the ordering structures, which would be an important guideline for the design of superior semiconducting polymers.

  A series of new quinoidal naphthodithiophenes, 2,7-bis(alpha,alpha-dicyanomethylene)-2,7-dihydronaphtho[1,2-b:5,6-b']dithiophenes, in which all the four fused aromatic rings are incorporated into the quinoidal system, were synthesized and evaluated as an n-channel organic semiconductor. Solution-processed field-effect transistors exhibited typical n-channel transistor characteristics with the mobility as high as 0.1 cm(2) V-1 s(-1), which is higher by more than I order of magnitude than those reported for isomeric quinoidal naphthodithiophenes having a naphthoquinoidal structure.

  We show that rational functionalization of the naphthodithiophene core in copolymers based on naphthodithiophene and naphthobisthiadiazole improves the solubility without an alteration of the electronic structure. Surprisingly, the introduction of linear alkyl chains brings about a drastic change in polymer orientation into the face-on motif, which is beneficial for the charge transport in solar cells. As a result, the present polymers exhibit high power conversion efficiencies of up to similar to 8.2% in conventional single-junction solar cells.
