中文摘要	mesoporous materials, as initiated at the beginning of the 1990s by the synthesis of mcm-41, were characterized with large pore channels sized from 1.5 to 10 nm, long-range order and surface areas higher than 700 m2/g. a breakthrough in lessening the diffusion hindrance has been made as compared with conventional microporous zeolites. most of the synthesis strategies to prepare mesoporous materials are based on the use of surfactant as pore structure-directing agent. gemini surfactants are a relatively new class of amphiphilic molecules containing two hydrophobic and two hydrophilic groups, connected by a linkage of variable length close to the hydrophilic groups. the general formula of gemini surfactant is [cmh2m+1(ch3)2n+-(ch2)s-n+(ch3)2cnh2n+1]·2br− (normally denoted cm-s-n). compared with the corresponding monovalent (single-chain, single-head-group) surfactants, gemini surfactants have some unique characteristics, such as high surface activity, low krafft point, and different behavior at the air/solution and solid/solution interfaces. several kinds of mesoporous materials have been synthesized by using gemini surfactants. herein, we report the synthesis of a novel fingerprint-like mesoporous aluminosilicate templated by a new gemini surfactant, c18-3-18 as structure-directing agent.
