Monomeric or polymeric compounds comprising at least one moiety of the formula (Ia) wherein X is CR, where R is H or a substituent as defined in claim
1,
or is another ketopyrrole moiety e.g. of the formula (1
b
) or (1
c
) with this moiety and all other symbols are as defined in claim
1,
show good solubility in organic solvents and excellent film-forming properties. In addition, high efficiency of energy conversion, excellent field-effect mobility, good on/off current ratios and/or excellent stability can be observed, when the polymers according to the invention are used in semiconductor devices or organic photovoltaic (PV) devices (solar cells).
单体或聚合物化合物至少包含式(Ia)中的一个基团,其中X为CR,其中R为H或按照权利要求1中定义的取代基,或为另一个酮吡咯基团,例如式(1b)或(1c),其中此基团和所有其他符号如权利要求1所定义,显示出在有机溶剂中良好的溶解性和优异的成膜性能。此外,当根据本发明的聚合物用于半导体器件或有机光伏(PV)器件(太阳能电池)时,可以观察到高效的能量转换、优异的场效应迁移率、良好的开关电流比和/或优异的稳定性。
