Side-Chain Azobenzene Polymers: Synthesis and Photochemical Properties
摘要:
A series of methacrylic monomers containing azobenzene moiety with alkyl spacer and different substituents is synthesized. Their photophysical and photochemical properties have been investigated. The photophysical properties of these compounds are investigated by 1H NMR, IR, and UV spectroscopies.

In this communication, a novel photochromic molecular switch DTE-2(Azo-CN) containing both dithienylethene and pushâpull azo chromophores was synthesized. The pushâpull azo chromophores can significantly accelerate the ring opening of the CâC bond of DTE closed isomer when irradiated with light far away from the maximum absorption band of the DTE closed isomer.
