Overview of Light-Sensitive Chromophores, Which Enable Reversible Light Response

Chromophore	Light response
Cinnamoyl	Ionization: isomerization to more hydrophilic species due to the electric charge generation or dimerization (171,172)
Azobenzene	Isomerization: upon UV irradiation, the compound in the trans conformation, having no dipole moment, is reversibly converted to the cis conformation with a dipole moment (167,170,173) Examples are: NNDMA, MOAB and the light-sensitive micellar formulation with hydrophilic P(tBA-co-AA) and hydrophobic PAzoMA (167,173)
Spirobenzopyran	Zwitterion: colorless spiropyran is converted into colored merocyanin upon UV (365 nm) irradiation and re-established under visible light (620 nm) (171)
Diarylethenes	Photocyclization: configuration of a ring system as a result of the formation of one new single bond (174)
Fulgides	Photochromism: switch from open colorless state to colored cyclic state (175)
Overcrowded alkenes	Chiroptical switch: switch to another conformation (176)

NNDMA N,N-dimethylacrylamide; MOAB methacryloyloxyazobenzene; P(tBA-co-AA), poly(tert-butyl acrylate-co-acrylic acid); PAzoMA poly(azobenzene methacrylate).
