MeO-2PACz

Product Name: MeO-2PACz, (2-(3,6-Dimethoxy-9H-carbazol-9-yl)ethyl)phosphonic acid
Catalog Number: ALCM2377770186
CAS Number: 2377770-18-6

Product Description

Chemical Structure of Br-2PACz

MeO-2PACz is a high-performance self-assembled monolayer (SAM) molecule designed for interface engineering in cutting-edge optoelectronic applications. A structural derivative of 2PACz, it incorporates a 3,6-dimethoxy-substituted carbazole moiety connected via an ethyl spacer to a phosphonic acid anchoring group. This configuration enables robust chemisorption onto metal oxide surfaces such as ITO and NiO.

Serving as a hole transport or extraction layer, MeO-2PACz provides excellent interfacial alignment between conductive oxides and active layers in both perovskite and organic solar cells. As a superior alternative to PEDOT:PSS, it enhances charge extraction, device stability, and overall efficiency.

When paired with an interfacial NiO layer, MeO-2PACz forms a compact, uniform SAM, minimizing interfacial defects and boosting shunt resistance for improved photovoltaic performance.

Key Features

Superior Interface Engineering: Forms strong, uniform SAMs on ITO, NiO, and other metal oxides
Solution Processable: Compatible with low-concentration, low-temperature spin-coating methods
Excellent Stability: Maintains excellent performance after long-term ambient aging
Broad Compatibility: Applicable to perovskite, NFA-polymer, and other organic photovoltaic platforms
