Catalyst-free Preparation of Melamine-Based Microporous Polymer Networks through Schiff Base Chemistry
J. Am. Chem. Soc., 2009, 131 (21), pp 7216–7217
Abstract

Recently, the synthesis of organic materials with high porosity has received considerable scientific interest, and various chemical approaches have been applied to the build-up of microporous polymer networks. In a novel catalyst-free process using Schiff base chemistry, melamine has been reacted with various di- and trivalent aldehydes to form a series of highly cross-linked microporous aminal networks with BET surface areas as high as 1377 m2/g and a NLDFT micropore volume of up to 0.41 cm3/g. It was shown that through the proper choice of the starting compounds the porosity of the final material can be fine-tuned. The materials contain up to 40 wt % of nitrogen and were also found to exhibit high thermal stability. Owing to the cheap and abundant monomers used in this study these networks are promising candidates for large-scale applications in gas storage, gas separation, catalysis, and sensing.

缩合不了,三聚氰胺的氨基类似于酰胺
