Correlating on-substrate prepared electrochromes with their solution processed counterparts – towards validating polyazomethines as electrochromes in functioning devices

Design rules for the preparation of low-cost hole transporting materials for perovskite solar cells with moisture barrier properties

“…[57] In our previous work we showed that the addition of LiTFSI is necessary to obtain good working devices when EDOT-OMeTPA is used. [5] Although there are several studies regarding electro-and chemical oxidation of azomethine-based dyes, [58][59][60][61] the effect of the oxidation by LiTFSI on azomethine-based HTMs and the effect on the conductivity have not been reported.…”

Extended benzodifuran–thiophene systems connected with azomethine junctions: synthesis and electronic properties

“…[18][19][20][21][22] As a further step in our contribution of developing donor-acceptor conjugated systems based on BDF, we report here on the synthesis and the electronic properties of extended BDF-thiophene derivatives 1a-d (Scheme 1). The electron donor ability of the thiophene units was strengthened by hexyloxy groups while electron withdrawing pentafluorophenyl, cyano and butylacetate groups were grafted on the BDF units.…”

Device Performance of Small-Molecule Azomethine-Based Bulk Heterojunction Solar Cells

“…10,11 Despite the aforementioned advantages, azomethines have received little attention as conjugated materials in organic electronics, such as field-effect transistors (OFET), electrochromic devices (ECD) and photovoltaics (OPV). [12][13][14][15][16] In 2010, the first azomethine-based OPV devices were demonstrated, where poly(azomethine)s were used as electrondonating materials. 14 While some progress was made using poly(azomethine)s for photovoltaic applications, their efficiencies remained relatively low.…”
