Py3

Product Name: Py3, (2-(Pyren-1-yl)ethyl)phosphonic acid
Catalog Number: ALCM1520027626
CAS Number: 1520027-62-6

Product Description

Chemical Structure of Py3

Py3 ((2-(Pyren-1-yl)ethyl)phosphonic acid) is a high-purity self-assembled monolayer (SAM) material specifically designed for use as a hole transport or extraction layer in perovskite and organic solar cells. Its molecular architecture consists of a phosphonic acid anchoring group linked by a short ethyl chain to a rigid, pyrene-based π-conjugated core. The lack of heteroatom substitution in the core contributes to its chemical inertness and structural rigidity, making it well-suited for stable interfacial engineering.

The rigid and planar polyaromatic backbone of Py3 facilitates dense molecular packing through strong π-π stacking, ensuring close interfacial contact with the perovskite layer. These features facilitate efficient hole extraction and minimize nonradiative recombination, leading to enhanced photovoltaic performance and long-term operational stability.

Py3 exhibits excellent compatibility with both small-area and large-area p-i-n perovskite solar cells. It has been employed as a high-performance hole-selective interlayer in solution-processed devices, typically using low-concentration formulations. As a robust alternative to PEDOT:PSS, Py3 offers improved device efficiency and thermal stability with the added benefit of straightforward solution processing.
