bis-lactam building block, 3,7-dithiophen-2-yl-1,5-dialkyl-1,5-naphthyridine-2,6-dione (NTDT), and a conjugated polymer P(NTDT-BDT) comprising NTDT as an electron acceptor and benzo[1,2-b:4,5-b′]dithiophene (BDT) as an electron donor are designed and synthesized for producing efficient organic solar cells. The thermal, electronic, photophysical, electrochemical, and structural characteristics of NTDT and
新型的电子接受性双内酰胺结构单元3,7-二噻吩-2-基-1,5-二烷基-1,5-萘啶-2,6-二酮(NTDT)和共轭聚合物P(NTDT-设计并合成了包含NTDT作为电子受体和苯并[1,2- b:4,5- b ']二噻吩(BDT)作为电子供体的BDT,以生产有效的有机太阳能电池。详细研究了NTDT和P(NTDT-BDT)的热,电子,光物理,电化学和结构特征,并与广泛使用的双内酰胺受体3,6-dithiophen-2-yl-2,5进行了比较。 -二烷基吡咯并[3,4- c]吡咯-1,4-二酮(DPPT)及其聚合物P(DPPT-BDT)。与DPPT衍生物相比,NTDT和P(NTDT-BDT)表现出明显更高的吸收系数,更深的最高占据分子轨道能级和更多的平面构象。基于P(NTDT-BDT)的整体异质结太阳能电池在高达18.51 mA cm –2的高短路电流(J sc)的情况下,功率转换效率高达8.1
