Abstract: UV-vis spectra of azobenzene containing carboxyl group were investigated by using density functional theory calculations. The calculation results show that substitutions of carboxyl groups have no obvious effect on the coplanarity of azobenzene. Compared with… read more here.

Abstract: In this work, 2-(bis(4-hydroxyphenyl)methyl)benzoic acid (BHPBA) was prepared by hydrolysis of phenolphthalein with addition of ferrous powder. Afterward, semiaromatic polyamides (SAPs) with varied carboxyl group content were prepared from BHPBA and the bisphenol 1,1-bis(4-hydroxyphenyl)-1-phenylethane (BHPPE)… read more here.
