Synthesis of Calix4resorcinarene-Based Bi-functional Hyper-structured Photorefractive Molecule by Click Chemistry
A bi-functional hyper-structured photorefractive (PR) molecules (CRA-PT-CSN) with a calix4resorcinarene (CRA) core was synthesized via click reaction between CRA-Alkyne and phenothiazine derivatives PT-CSN-N3 (shown in Scheme 1), where phenothiazine served as the charge transport group and p-nitrobenzylcyanide provided electro-optical response.PT-CSN-N3 was synthesized through Knoevenagel reaction between phenothiazine and p-nitrobenzylcyanide.The chemical structures of the intermediate products and target products are characterized by 1H (13C) NMR,IR, EA, UV-vis, GPC, TG, etc.CRA-PT-CSN exhibits general solubility and excellent thermal stability.However, its glass-transition temperature is low, which is desirable to achieve better PR performance through an orientation mechanism.Its PR performance was measured through two-beam coupling (TBC)experiment using the optically transparent films of CRA-PT-CSN doped with C60 and polyvinyl carbazole.
