摘要

Abstract

New types of polyamides containing pendent triaryl pyridine groups were successfully synthesized by direct polycondensation of a symmetry diamine

(4-(4-(2

6-diphenylpyridin-4yl)phenoxy)phenyl)-3

5-diaminobezamide (DPDAB)

and various aromatic and aliphatic dicarboxylic diacids in NMP using triphenyl phosphate (TPP) and pyridine as catalyst. The diamine and all the prepared polyamides were fully characterized by using FT-IR

H-NMR

UV-Vis spectroscopy

fluorimetry and elemental analysis. The inherent viscosity of polyamides ranged from 0.45 dL/g to 0.68 dL/g. All the polymers exhibited solubility in common polar aprotic solvents such as NMP

DMAc

DMF

DMSO

pyridine

HMPA

and even in less polar solvents such as THF and

-cresol at room temperature. Thermal properties of polyamides were evaluated by means of DSC

DMTA and TGA. These polymers showed glass transition temperatures (

) in the range of 138-210℃. Their initial decomposition temperature (

) varied from 265℃ to 310℃ under N

. The dilute solution (0.2 g/dL) of polyamides in DMF exhibited fluorescence emission with

max

in the range of 470-550 nm.
