Abstract

The enhancement of the cycloreversion reaction of photochromic fulgides was observed not by the femtosecond laser but by the picosecond laser exposure. The excitation intensity effect of the reaction profiles revealed that the successive multiphoton absorption process leading to higher excited states opened the efficient cycloreversion process.
