spirobifluorene positionalisomers possessing a para-, meta- or ortho-linkage. The remarkable and surprising impact of the ringbridging and of the linkages on the electronic properties of the regioisomers has been particularly highlighted and rationalised. The impact of the ringbridging on the photophysical properties has been stressed with notably the different influence of the linkages and the bridge on the
