Aromaticity PNG: 11 free images
Rings with alternating double bonds in every variant: plain benzene, aniline with its amino group, fused systems like naphthalene and anthracene, and rings with nitrogen or oxygen built in, from pyridine and indole to benzofuran.

Reading the rings
A hexagon with a circle or three double bonds is the aromatic core. When a nitrogen sits in the ring, the compound becomes a heterocycle, and the drawings show exactly where it is placed. That makes the set useful for explaining why pyridine behaves differently from benzene.
Fused systems
Naphthalene, quinoline and acridine stack rings side by side. Put them in a row to show how a molecule grows and how its properties change with each added ring.
Pi stacking
One image shows benzene rings lying on top of each other, the way they attract in crystals and in DNA. It is the only diagram here that goes beyond a single molecule and suits a lecture on intermolecular forces.
Questions and answers
Are all aromaticity images really transparent?
All 11 images carry a real alpha channel. On the image page you can switch the backdrop to white or dark to see the edges.
Are there large files for print?
In aromaticity the sizes run from 601 to 1 257 px on the long side. Large ones are easiest to find with the “Largest” sort or the minimum-width filter.
How many files can I download?
No sign-up needed. The file is served after a short wait on the download page.
Can I use aromaticity images commercially?
Terms depend on the specific image. We neither sell files nor issue licences; for commercial work check the source named on the image page.
