Molecular Cage with Dual Outputs of Photochromism and Luminescence Both in Solution and the Solid State.

ACS Applied Materials and Interfaces, 2023
The rational design of stimuli-responsive materials requires a deep understanding of the structure-activity relationship. Herein, we proposed an intramolecular conformation-locking strategy─incorporating flexible tetraphenylethylene (TPE) luminogens into

Tunable Photochromism of Spirooxazine in the Solid State: A New Design Strategy Based on the Hypochromic Effect

Advances in Materials, 2022
As an important organic photofunctional material, spirooxazine (SO) usually does not exhibit photochromism in the solid state since the intermolecular π–π stacking impedes photoisomerization.

Photochromic polypeptides

Journal of Polymer Science Part A-1: Polymer Chemistry, 1970
AbstractTwo photochromic polypeptides were synthesized by reaction of 1‐(4‐iodobutyl)‐3,3‐ dimethylindolindolino‐6′‐nitrobenzospiropyran with poly‐L‐tyrosine; their molar contents on photochromic units were 27.3 and 44.7%. The spectra of the photo‐induced merocyanines and their decoloration kinetics were compared with these of the monomeric model ...
