摘要:

设计、合成了5个酰亚胺镓萘酞菁电子受体(Cl-GaNcTI、OH-GaNcTI、R3SiO-GaNcTI、F5PhO-GaNcTI和QLO-GaNcTI),并将其作为受体材料应用于制备体相异质结有机太阳能电池。在波长300~1100 nm范围内,5种受体材料具有较强的近红外吸收,最大消光系数高达6.18×105 L/(mol·cm),较低的最低未占据分子轨道(LUMO)能级(-3.9 eV)和良好的热稳定性(热分解温度Td>320 ℃),在萘酞菁轴向上引入长链取代基能够有效地减弱分子聚集性,均可用作体相异质结有机太阳能电池的受体材料。

Abstract:

Five gallium naphthalocyanines, Cl-GaNcTl, OH-GaNcTl, OSiR3-GaNcTI, F5Ph-GaNcTI and QL-GaNcTI, have been designed and synthesized as acceptor materials for bulk heterojunction organic solar cells (BHJ OSCs). They exhibit strong near-infrared absorption at 300~1100 nm, a high maximum extinction coefficient of 6.18×105 L/(mol·cm), a low minimum unoccupied molecular orbital (LUMO) energy level of -3.9 eV, and good thermal stability (Td>320 ℃). The introduction of long chain substituents in the axial direction of naphthalocyanine is found to be effective in decreasing molecular aggregation. All of them could be used as acceptor materials for bulk-phase heterojunction organic solar cells.

Key words: Naphthalocyanine, Organic solar cell, Electron acceptor material, Near-infrared absorption
