Outline of Final Research Achievements

We have designed and synthesized a series of photopolymerizable bisanthracene molecules in which two anthracene moieties are connected with a spacer. Thin films of bisanthracenes showed solid state polymerization due to the intermolecular dimerization upon irradiation with ultra-violet light. When the film was irradiated with spatially patterned ultra-violet light, regular surface reliefs with the same period of the patterned light were produced due to the lateral mass transfer from the shaded areas to the irradiated areas.
