摘要

<正>A novel soluble regular ladder poly（benzoyl-3-aminopropyl） silsesquioxane （LPBAS） was facilely prepared under effective assistance of concerted H-bonding self-assembly of amido groups of side chains and silanol groups

respectively

of a new template monomer [1

3-bis（benzoyl-3-aminopropyl）-1

3-tetraethoxydisiloxane] （M）. The ordered ladder structure of LPBAS is manifested in: （1） the presence of two Bragg peaks representing the ladder width （d） and ladder thickness （t） in X-ray diffraction （XRD） pattern; （2） narrow base-line width （w = 6） of resonance absorption for -CH2SiO3/2 moiety in 29Si-NMR and （3） high glass transition temperature Tg = 112℃in differential scanning calorimetry （DSC） analysis.
