Electro-optical and electrochemical properties of poly(1-hexyne)

Synthesis of novel helical poly(N-propargylamides) containing azobenzene pendant groups and effects of substitution groups on azobenzene on the stability of helix

“…Their cis and trans forms can be reversibly isomerized upon photoirradiation. Many polymers bearing azobenzene chromophores have been explored extensively because of the unique optical properties [25][26][27][28][29]. Recently, some helical poly(N-propargylamides) containing azobenzene moieties have been synthesized, and the reversible transformation of higher order structures triggered by azobenzene isomerization were studied [6,[30][31][32].…”
