ves of these fluorohelicenes have been synthesized by the photocyclodehydrogenation of 1-fluoro-11-styrylbenzo~c]phenanthrenes (Table 2) and l-fluoro-13-styrylpentahelicenes (Table 4) respectively. The ohotocyclisations to heptahelicenes were accompanied in five cases, by a side reaction, namely a p
