From Comparative Examples 1 to 3, it can be seen that even when the homogeneous transition metal complex catalyst is increased, the weight average molecular weight of the conjugated polymer is increased rather than increased.
- the weight average molecular weight of the obtained conjugated polymer is lower than that in the examples, and the yield is also low because compound E2 is cross-coupled with compound E1 in the reaction system. It is thought that this is because the trimethylstannyl group is easily eliminated from the compound E2 rather than causing a ring reaction.
- the yield of the obtained conjugated polymer is 85 to 86. %, but the weight average molecular weight Mw of the conjugated polymer obtained was only 2.2 ⁇ 10 4 to 3.1 ⁇ 10 4 . Further, it can be seen that the reaction is completed in about 2 hours from the start of the reaction.
- the yield of the obtained conjugated polymer is as high as 85 to 86%, but the weight average molecular weight of the obtained conjugated polymer is lower than in the examples.
- the compound E2 reacts rapidly with the compound E1 in the reaction system in the vicinity of the heterogeneous transition metal complex catalyst, it becomes porous when it reaches a certain size (about 2.0 ⁇ 10 4 ). It is considered that the polymer synthesis does not extend because it becomes impossible to contact the active center of the heterogeneous transition metal complex catalyst existing in the polymer.
- the yield of the obtained conjugated polymer is 71 to 80%, which is markedly improved as compared with the case where only the homogeneous transition metal complex catalyst is used (Comparative Examples 1 to 4 and 18). I understand that. That is, it can be seen that the manufacturing method of the present application has high reproducibility.

- ⁇ 10 4 to 1.0 ⁇ 10 5 was very high, and the yield of the obtained conjugated polymer was as high as 71 to 73%. This is presumably because the phosphine ligand present in the reaction system is coordinated to the palladium catalyst supported on the porous polymer carrier in the reaction system to become a heterogeneous transition metal complex catalyst.

- a solidification catalyst (Fibrecat 1026) which is a heterogeneous transition metal complex catalyst
- the weight average molecular weight Mw of the obtained conjugated polymer was as high as 1.8 ⁇ 10 5 compared to Comparative Example 19, and the obtained conjugated polymer was also obtained. It can be seen that the yield of is as high as 74%.
- the photoelectric conversion element using the conjugated polymer obtained in the above examples does not depend on the type of the conjugated polymer compared to the photoelectric conversion element using the conjugated polymer obtained in the comparative example, It can be seen that the photoelectric conversion efficiency has improved. That is, it can be seen that the photoelectric conversion element using the conjugated polymer having a large weight average molecular weight improves the photoelectric conversion element performance as compared with the photoelectric conversion element using the conjugated polymer having a small weight average molecular weight.
- a conjugated polymer having a higher molecular weight can be obtained by using a monomer coupling reaction in combination with a homogeneous and heterogeneous transition metal complex catalyst, and a photoelectric conversion element having excellent photoelectric conversion efficiency can be obtained by using the conjugated polymer. Therefore, it is suitable for solar cell and its module use, and can be used as an energy source with low environmental load.

本発明におけるカップリング反応の例としては、(1)酸化的ホモカップリング反応、(2)C-H結合活性化反応、(3)クロスカップリング反応、(4)C-ヘテロ原子のカップリング反応、などが挙げられる。
以下に、本発明のカップリング反応において利用できる均一系遷移金属錯体触媒について説明する。カップリング反応を円滑に進行させるために、均一系遷移金属錯体としてはカップリング用遷移金属錯体を用いることが好ましく、特に遷移金属として後周期遷移金属を用いることが好ましい。
パラジウム錯体は、パラジウム(0)が重要な触媒種であるが、一般に、空気中で不安定で分解されやすい。一方、パラジウム(II)は安定であり、配位子との共存により容易にパラジウム(0)に変換され系中で活性種を発生させる。なお、系中でパラジウム(II)錯体と配位子とから活性なパラジウム(0)錯体を作製する場合、パラジウム(II)錯体とパラジウム(0)錯体との2種類の錯体が用いられているのではなく、1種類のパラジウム錯体が用いられているものと考える。
ニッケル触媒としては、Negishiら,Chemistry of Organozinc Compounds(Pt.1),pp.457-553,(2006)や、Takahashiら,Modern Organonickel Chemistry,pp.41-55(2005)などに記載のものを用いることができる。
鉄触媒の例としては、Fe(acac)3、Fe(dmb)3、[Fe(C2H4)4][Li(tmeda)]2、[(FeCl3)2(tmeda)3]などが挙げられる。
銅触媒の例としては、CuOAc、(CuOTf)2、CuTC、Cu(MeCN)4PF6、CuBr・Me2S、Cu(neocup)(PPh3)などが挙げられる。
以下に、本発明のカップリング反応において利用できる不均一系遷移金属錯体触媒について説明する。カップリング反応を円滑に進行させるために、不均一系遷移金属錯体としてはカップリング用遷移金属錯体を用いることが好ましく、特に遷移金属として後周期遷移金属を用いることが好ましい。後周期遷移金属の中でも特に、パラジウム、ニッケル、鉄、及び銅を含む不均一系遷移金属錯体を用いることが、反応性を向上させるために好ましい。
本発明のカップリング反応において用いられる1種以上のモノマーのそれぞれは、ドナー性又はアクセプター性を有する共役化合物、又は芳香族化合物であることが好ましい。より好ましくは芳香族化合物である。
式(A4)において、X12及びX13はそれぞれ独立に、16族元素から選ばれる原子を表す。得られる共役高分子の半導体特性の観点から、X12及びX13は酸素原子又は硫黄原子であることが好ましく、硫黄原子であることが特に好ましい。
R46は、R1Xとして前述した基と同様の基が挙げられる。
本発明のモノマーの製造方法は特に限定はなく、公知の方法に従って製造することができる。例えば、式(A7)で表される化合物は、J.Mater.Chem.,21,3895(2011)、及びJ.Am.Chem.Soc.,130,16144-16145(2008)に記載の方法に準じて製造することができる。
次に、カップリング反応の反応条件について詳しく説明する。
具体的には、TOFが大きい遷移金属錯体触媒を均一系遷移金属錯体触媒とし、TONが大きい遷移金属錯体を不均一系遷移金属触媒としてもよく、TOFが大きい遷移金属錯体触媒を均一系遷移金属錯体触媒とし、TONが大きい遷移金属錯体を不均一系遷移金属触媒としてもよい。
2種以上の遷移金属錯体触媒について、一方は大きなTON(ターンオーバー数)を示し、他方は高い反応性(例えば高い反応速度(TOF))を示すことが、高分子量の共役高分子を得るために好ましい。また、それぞれの遷移金属錯体触媒は、同種の遷移金属を有することが、反応を複雑にしないために好ましい。
反応式(1)に示すように化合物A1と化合物A2とをカップリングさせる場合、化合物A1に対する化合物A2とのモル比は、得たい共役高分子の分子量分布に依存するが、通常0.75以上、好ましくは0.85以上であり、一方、通常1.3以下、好ましくは1.2以下である。
反応に用いる溶媒としては、例えば、ペンタン、ヘキサン、ヘプタン、オクタン、若しくはシクロヘキサンなどの飽和炭化水素;ベンゼン、トルエン、エチルベンゼン、若しくはキシレンなどの芳香族炭化水素;クロロベンゼン、ジクロロベンゼン、トリクロロベンゼン、若しくはフルオロベンゼンなどのハロゲン化芳香族炭化水素;メタノール、エタノール、プロパノール、イソプロパノール、ブタノール、若しくはt-ブチルアルコールなどのアルコール類;水;ジメチルエーテル、ジエチルエーテル、メチル-t-ブチルエーテル、テトラヒドロフラン、テトラヒドロピラン、若しくはジオキサンなどのエーテル類;ブチルアミン、トリエチルアミン、ジイソプロピルエチルアミン、ジイソプロピルアミン、ジエチルアミン、ピロリジン、ピペリジン、若しくはピリジンなどのアミン系溶媒;又は、N,N-ジメチルホルムアミド、ジメチルスルホキシド、若しくはN-メチルピロリドンなどの非プロトン性極性有機溶媒などが挙げられる。生成する共役高分子の溶解性を向上させるために、これらの溶媒を一種を単独で用いてもよいし、二種以上の溶媒を混合して用いてもよい。
モノマー及び生成する共役高分子の劣化を防ぐために、不活性ガス下で反応を行うことが好ましい。特に、窒素雰囲気下、又はアルゴン雰囲気下で反応を行うことが好ましい。しかしながら、酸化的カップリングを行う場合は、不活性ガス下で反応を行う必要はない。
反応温度は特に限定されないが、通常は、室温以上、溶媒の沸点以下の温度で行う。反応速度を上げるために、オートクレーブ又はマイクロ波などを用いて、加圧及び/又は加熱を行ってもよい。
反応時間はモノマーの反応性に依存するが、短い時間で反応を十分に完結させる観点から、通常5分以上、好ましくは30分以上、より好ましくは1時間以上であり、一方、通常48時間以下、好ましくは24時間以下、より好ましくは15時間、さらに好ましくは12時間、ことさらに好ましくは6時間、特に好ましくは3時間である。この時間に、後述する末端処理に要する時間は含まない。通常は、分析GPCを用いるなどの方法で反応が完結したか否かを確認し、後述する末端処理を行う。
本発明の製造方法の反応スケールについて、特段の制限はないが、500mg以上5g以下程度の小スケールでも、5gより大きい大スケールでもよい。大スケールの上限に特段の制限はない。本発明の製造方法は、短時間でモノマーをオリゴマーに変換し、モノマーの活性基が分解することを防ぎ、活性基の分解速度は低下する傾向にあるオリゴマーをカップリング反応で重合するため、本発明の製造方法は、従来の反応系と比較して、より安定した合成系、つまり再現性が高い反応系であると考える。ゆえに、本発明の製造方法は、再現性が求められる大スケールにより適した反応系であると考える。
<3.8 塩基>
反応溶液には、モノマー、触媒、及び溶媒の他に、さらに塩基を加えてもよい。塩基を加えることは、反応速度が向上しうる点で好ましい。塩基の例としては、炭酸水素ナトリウム、炭酸ナトリウム、炭酸カリウム、炭酸セシウム、炭酸カルシウム、リン酸カルシウム、水酸化ナトリウム、水酸化カリウム、水酸化セシウム、フッ化セシウム、若しくはフッ化カリウムなどの無機塩基;又は、カリウムt-ブトキシド、ナトリウムt-ブトキシド、ナトリウムメトキシド、ナトリウムエトキシド、ピリジン、ルチジン、ジ(t-ブチル)ピリジン、トリエチルアミン、リチウムジイソプロピルアミド、リチウムヘキサメチルジシラジド、t-ブチルリチウム、若しくはn-ブチルリチウムなどの有機塩基が挙げられる。特に、反応をより促進しうる点で、セシウム塩及びフッ化物塩を加えることは好ましい。
反応溶液には、モノマー、触媒、及び溶媒の他に、さらに相間移動触媒を加えてもよい。相間移動触媒の例としては、アンモニウム塩、ヘテロ環アンモニウム塩、ホスホニウム塩などが挙げられる。2層系の溶媒を用いる場合、トリアルキルアンモニウムブロミド、トリアルキルアンモニウムクロリド、トリアルキルアンモニウムアイオダイド、テトラブチルホスホニウムブロミド、テトラエチルアンモニウムホスホニウムクロライド、Aliquat、又はイオン性液体などを相間移動触媒として用いてもよい。
カップリング反応が終了すると、公知の方法、例えば、水でクエンチした後に有機溶媒で抽出し、この有機溶媒を留去するなどの通常の後処理により、粗製の共役高分子を得ることができる。その後、粗製の共役高分子から金属を取り除くために、再沈精製、ソックスレー抽出、ゲル浸透クロマトグラフィー、又はスキャベンジャーにより、純化処理をすることが好ましい。中でも再沈法は、大量の共役高分子を精製できることから好ましい。
重合反応後の共役高分子に対しては、末端処理を行うことが好ましい。共役高分子の末端処理を行うことにより、共役高分子に含まれる、臭素(Br)若しくはヨウ素(I)などのハロゲン原子、又はアルキルスタニル基のような末端残基(上述のX1~X4)の残存量を減らすことができる。この末端処理を行うことは、半導体性能及び耐久性の点でよりよい性能の共役高分子を得ることができるために、好ましい。
