Enhancement of characteristics of a functionalized oligophenylene by acid hydrolysis modification

الملخص EN

New modified oligophenylene was prepared by acid hydrolysis of a functionalized oligophenylene (OMPA).The latter was obtained by (4-methoxy phenyl) acetonitrile electrochemical oxidation.

The resulting modified oligomer (OAC) was characterized by various spectroscopic techniques: NMR, FTIR and UV.

The thermal study showed that the modified material exhibited a higher thermal stability compared with OMPA.

Further, the optical study revealed that in solution, the emission was blue-shifted when compared with the non-modified oligomer emission and that the optical gap changed from 3.1 eV to 2.75eV.

In chloroform solution, photoluminescence was again blue-shifted by 90 nm, which is probably due to an interaction between the oligomer chains.
