MeO-4PACz

Product Name: MeO-4PACz, (4-(3,6-Dimethoxy-9H-carbazol-9-yl)butyl)phosphonic acid
Catalog Number: ALCM2922526563
CAS Number: 2922526-56-3

Product Description

Chemical Structure of MeO-4PACz

MeO-4PACz (4-(3,6-Dimethoxy-9H-carbazol-9-yl)butyl)phosphonic acid) is a high-performance self-assembled monolayer (SAM) material developed for use as a hole transport or extraction layer in advanced perovskite and organic photovoltaic devices. It comprises a hydrophobic, electron-rich 3,6-dimethoxycarbazole core, a flexible butyl linker, and a phosphonic acid anchoring group, which ensures strong chemical bonding to metal oxide substrates such as ITO.

As a methoxy-substituted analog of Me-4PACz, this material offers enhanced surface wettability and improved deposition reproducibility—critical for achieving uniform perovskite layers and high device yields. These attributes make it particularly well-suited for inverted (p-i-n) perovskite solar cells and non-fullerene acceptor (NFA)-based polymer solar cells.

The extended alkyl spacer in MeO-4PACz allows for co-anchoring of smaller molecules such as (aminomethyl)phosphonic acid (AMP), which can infiltrate and fill nanoscale voids within the monolayer. This interfacial densification improves surface passivation, minimizes trap-assisted recombination, and ultimately enhances device stability and operational efficiency.

Thanks to its excellent solubility and solution-processability at low concentrations (typically 1 mM), MeO-4PACz provides a scalable, low-temperature alternative to PEDOT:PSS. Its compatibility with various wet-coating techniques enables reproducible interface engineering in both research and large-scale fabrication environments.
