Colour edition
For a colour printer. The page is white and the header is pale, so it uses very little ink.
Free poster · A3 (297 × 420 mm)
Functional groups at a glance
The few atoms that decide how a molecule behaves, with a real medicine for each, a colour code, and a glow that shows you where to look. Pin it up and you can read almost any drug.

Black and white edition
Made for black-and-white printers. Patterns replace the colours, so every family is still easy to tell apart.
Print at A3 or larger. A2 is best for a classroom wall. On A4 the small text becomes too small to read comfortably.
Make it yours
Put your name on it
The poster has a plate that says This poster belongs to. Type your name and we write it on the line for you. It all happens on your own device, so your name is never sent to us.
Sign in and we will fill in your name for you.
Prefer a pen? Download the plain poster above and write on the line. Bangla names work too, if your device has a Bangla font (most phones do).
Printing tips
Get a good print without spending much
Choose the size
A3 is the design size, and A2 is best for a wall. Most print shops can do both. Choose "Actual size" or "Fit to page" in the print settings.
Save ink
The page is white and the header is pale, so even the colour edition uses little ink. On a black-and-white printer, use the black-and-white edition.
Print one test
Screens and printers show colours differently. Print one copy first and hold it at arm's length. It should be easy to read.
In the classroom
Four ways to use it
Medicine hunt. Bring in an empty medicine pack, find the name of the drug, and spot its groups on the poster.
Group of the day. Pick one card each lesson and find that group in a new molecule.
Check it in the screener. Paste a drug into the compound screener and see its flagged groups.
Draw and colour. Students draw paracetamol and colour its three groups, as on the poster. See the Molecule of the Month for more.
Free to print and use in classrooms, labs and reading rooms, with Chem2Cure credited. Please do not sell it. Check the facts against your textbook.
