Br-2PACz

Product Name: Br-2PACz, (2-(3,6-dibromo-9H-carbazol-9-yl)ethyl)phosphonic acid
Catalog Number: ALCM2762888117
CAS Number: 2762888-11-7

Product Description

Chemical Structure of Br-2PACz

Br-2PACz, formally known as 2-(3,6-dibromo-9H-carbazol-9-yl)ethyl)phosphonic acid, is a high-performance self-assembled monolayer (SAM) material designed for interface engineering in next-generation optoelectronic devices. As a dibrominated derivative of 2PACz, it features a π-conjugated carbazole moiety and a phosphonic acid anchoring group, ensuring strong and stable binding to metal oxide surfaces such as indium tin oxide (ITO).

Carbazole-based SAMs like Br-2PACz are widely recognized for their ability to tailor interfacial properties in perovskite solar cells, tandem photovoltaics, and other thin-film electronic devices. By modifying electrode surfaces, they facilitate efficient charge transport and improve overall device architecture without introducing additional processing complexity.

Br-2PACz is solution-processable at low concentrations (typically 1 mM), making it highly compatible with scalable, and low-temperature deposition techniques. Its molecular structure enables precise tuning of surface energy levels, offering a compelling alternative to conventional hole transport materials such as PEDOT:PSS in organic and hybrid solar cells.

Key Features

High-purity SAM material for interface engineering
Strong phosphonic acid anchoring to oxide substrates (e.g., ITO)
Electron-rich carbazole terminal group for improved surface energetics
Enhances charge selectivity and reduces recombination losses
Solution-processable at low concentrations
Ideal for perovskite and organic photovoltaic applications
