Synthesis and evaluation of new isoquinoline diimide derivatives as small molecule acceptors for organic solar cells

Year: 2025
Type: article
Abstract: In this work we explore the use of the method of oxidation and heterocyclization of naphthalene diimides (NDIs) to obtain five novel isoquinoline diimide derivatives ( IQDI 3 – 7 ) as new small molecule acceptors. These derivatives comprise a main core based on triphenylamine (TPA) as electron-donor linked to an isoquinoline diimide moiety as a new electron-acceptor ( IQDI 3 ). The effect on the electronic properties of a further functionalization on TPA achieving A-D-A architectures with additional electron acceptors moieties such as carbonyl group ( IQDI 4 ), 3-methylrhodanine ( IQDI 5 ), 1,3-indandione ( IQDI 6 ) and malononitrile ( IQDI 7 ) was studied. Their electrochemical and optoelectronic properties as well as their performance in photovoltaic devices using J52 as electron-donor polymer were studied being IQDI 6 the compound that showed the best PCE % value.
