Porous organic polymers filter toxins from the air

In a search for the next generation of filtration materials, for use in devices such as gas masks, a group of US scientists has synthesised a series of porous organic polymers (POPs) bearing metal-catecholate groups. By changing the molecular building blocks the researchers were able to tailor the materials to hydrogen bond to, and consequently remove, different toxins, such as ammonia.

POPs are very similar in nature to metal-organic frameworks (MOFs) but do not suffer from such instability, particularly towards water, making them ideal for use as filters in real-word environments.
