<p>Quantum yields can be determined by global fitting of prolonged change of concentration against absorbed photon numbers. Quantum yields of synthesized amphiphilic diarylethene in solution and in suspension were analyzed by the global fitting upon irradiation with UV (365 nm) light. Quantum yields of cyclization and cycloreversion reaction in acetonitrile were obtained as 0.59 and 0.013, respectively using the absolute method. In suspension, quantum yield of cyclization was determined as 0.76 using the relative method. The result indicates that the preferred conformation of the open-ring isomer in the aggregate was antiparallel due to the hydrophilic chains and hydrogen bond.</p>
