摘要：

Poly(phenylenebutadiynylene) derivatives (PPBs) were synthesized and carbonized by thermolysis from room temperature to 900 degrees C under flowing argon, affording porous carbonaceous materials in high yields. The nanostructures and the graphitization behavior of the carbonized materials were investigated by XRD, Raman, electron microscopy, and N, adsorption methods. The carbonized material was made up with basic structural units of carbonaceous layers having an average dimension of 2-4 nm and a wide interlayer distance of 0.4 nm. The nano-space was created by organization of the basic structural units, which resulted in microporosity of the material. The carbonized materials were hard to graphitize by heat treatment of higher temperature. (c) 2006 Elsevier Ltd. All rights reserved.
