Improved durability of norbornadiene derivatives using antioxidized reagent
It was found that improvement in durability of NBDs against degradation during repeated cycles of photoisomerization of NBDs to QCs and thermal reversion of QCs to NBDs could be achieved by an antioxidized reagent. Hindered amine derivative was the most effective.
