8‐Hydroxy‐9, 15‐dihydro‐7 H ‐diindeno [2, 1‐b;2′, 1′‐g] fluorene, a derivative of a new mono‐angular diindenofluorene system, has been synthesised in 6 steps (overall yield 42%) starting from 9‐oxo‐fluorene‐1‐carbaldehyde and acetophenone. The corresponding hydrocarbon could not be obtained by reductive scission of the hydroxyl group.
