Synthesis of azobenzene-functionalized star polymers via RAFT and their photoresponsive properties

Alam, Md. Zahangir,Shibahara, Akihisa,Ogata, Tomonari,Kurihara, Seiji

, p. 3696 - 3703 (2012/02/05)

Azobenzene-functionalized star polymers were synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization. First, azobenzene-functionalized linear macro chain transfer agents (Macro-CTA) were synthesized by RAFT polymerization of 6-[4-(4′-Methoxyphenylazo)phenoxy] hexylmethacrylate (MAz6Mc) using 2-(2′-cyanopropyl)dithiobenzoate (CPDB) as RAFT agent in presence of AIBN as initiator in anisole. Subsequently, star azopolymers were synthesized by polymerization of a difunctional azomonomer, BMA2Az, with resultant Macro-CTA in presence of AIBN as initiator in anisole. Star azopolymers were characterized by GPC and spectroscopic methods. Thermal properties of star azopolymers were determined by DSC and TMA. Molecular weight versus conversion and molecular weight versus polymerization time attest to living polymerization characteristics. Photoisomerization behaviors of star azopolymers were studied by irradiation of both UV and visible light. Surface relief gratings were inscribed on star azopolymer films upon exposure to an interference pattern of (RCP + RCP) Ar+ laser. A diffraction efficiency of 20% was obtained by exposure of Star-8 K(2.6 K) polymer film to an (RCP + RCP) Ar+ laser for about 30 min. Surface relief grating structures were investigated by AFM and polarized optical microscopy.

SYNTHESIS AND PROPERTIES OF SIDE-CHAIN LIQUID CRYSTALLINE POLYMERS CONTAINING AZOBENZENE MESOGENS

Angeloni, Annino Sante,Campagnari, Ilaria,Caretti, Daniele,Carlini, Carlo,Altomare, Angelina,et al.

, p. 171 - 178 (2007/10/02)

The synthesis and phase behaviour of side-chain liquid crystalline polymers containing the trans-azobenzene mesogenic unit are described.Depending on the structure of the repeating unit, the polymers give rise to nematic mesophases and/or different smectic modifications.The liquid crystalline properties of the polymers are discussed with respect to the influence of the polymer backbone nature, chemical constitution and length of the spacer segment, and type and length of the para substituent on the azobenzene moiety.Indications on the UV absorption and photoisomerization behaviour of trans-azobenzene containing polymers are also provided.
