U+23E3 "⏣" Benzene Ring with Circle Unicode Character
Unicode Version 17.0
⏣
U+23E3 "⏣" Benzene Ring with Circle is a graphical symbol that depicts a hexagon with a circle inside it, which represents a common notation for the benzene molecule in organic chemistry, indicating the molecule's delocalized pi electrons. It was added to the Unicode standard as part of the Miscellaneous Technical block, where it serves primarily as a specialized icon for chemical diagrams and engineering schematics rather than as a letter or number. Its design differs slightly from the simple benzene ring symbol, as the inner circle is a distinct geometric element, making it useful in software and documentation that require a precise, non-textual representation of this aromatic compound.
