 DESCRIPTION:

The only commercially available PTAS organics. To date our PTAS materials enable many researchers to synthesize 2D CVD materials. Perylene-3,4,9,10-tetracarboxylic acid tetrapotassium acid salt (PTAS) acts as a seed for monolayer metal sulfides by catalyzing reduced metal oxides onto various substrates. This polymer has been synthesized at our facilities from perylene-3,4,9,10-tetracarboxylic dianhydride (PTC-DA) and the final product has been purified and filtered x7 times to reach 99.997% purity. Growing metal sulfides on various oxide surfaces becomes much easier after spin coating 10-1000 microMolar PTAS onto desired substrates. Each order contains PTAS solid (powder form) in a Argon sealed glass vial that is sufficient to produce large volumes (~1 liter) PTAS DI solution for successful CVD growth.

This product is sold in solid form to enable our customers to prepare their own PTAS concentrations at desired amounts.
