Compounds of formula (I) wherein EWG is an electron withdrawing group or combination of groups, R1 and R2 are each independently selected from the group consisting of alkyl, aromatic or heteroaromatic groups, or R1 and R2 may together comprise a linked alkyl, aromatic or heteroaromatic group. R3 and R4 are each independently selected from the group consisting of alkyl, alkoxy or H, or R3 and R4 may together comprise a divalent alkyl group, a divalent alkoxy or alkyldioxy group, or R3 and R4 may together comprise a heterocyclic, heteroaromatic or aromatic group linked or fused to the thiophene group and n is an integer between 2 and 10. The compounds are capable of charge transportation and have application in organic photovoltaic devices such as dye sensitised solar cells.
化学式为(I)的化合物,其中EWG是一个电子吸引基团或基团组合,R1和R2各自独立地选自由烷基,芳香基或杂环芳香基组成的群组,或者R1和R2可以共同组成一个连接的烷基,芳香基或杂环芳香基。R3和R4各自独立地选自由烷基,烷氧基或氢,或者R3和R4可以共同组成一个二价烷基,二价烷氧基或烷基二氧基基团,或者R3和R4可以共同组成一个与噻吩基团连接或融合的杂环,杂环芳香或芳香基团,n是介于2到10之间的整数。这些化合物能够传递电荷,在有机光伏器件如染料敏化太阳能电池中有应用。
