    摘要: PROBLEM TO BE SOLVED: To provide a method for forming guanidine groups not chelate-reacting with metal cations existing in solutions on a carbon nanotube, and to provide a method for forming guanidine groups on a carbon nanotube as a method for more increasing the dispersibility of carbon nanotube. SOLUTION: A method for attaching carbon nanotubes having guanidine groups formed thereon to a substrate comprises a step for coating the substrate with a crown ether-having polymer, a step for drying the crown ether-having polymer layer coated on the substrate in a semi-dry state, and a step for coating the semi-dry polymer layer with a solution containing the carbon nanotubes having the guanidine groups formed thereon. The carbon nanotubes having the guanidine groups formed thereon and produced by the method are uniformly dispersed in solutions by the hydrogen bond of the guanidine groups to the hydrogen bond-formable solvent molecules. The guanidine groups are selectively bound to the crown ether, and the property is utilized to vertically arrange the carbon nanotubes having the guanidine groups formed thereon on the substrate at a constant distance.

    摘要: PROBLEM TO BE SOLVED: To obtain a new compound useful as an organic base precursor having the rapidity of producing a base at the time of heating compatible with the stability during the preservation. SOLUTION: This compound is represented by formula I [R to R are each H, an alkyl, an alkenyl, an aralkyl or an aryl; Z is a substituent group having a value of σ of >=0 when defined by the Hammett's equation; [(i)+(j)] is 3 and (i) is 1 or 2] or formula II (R to R are each same as R to R ), e.g. a compound represented by formula III. The compound represented by formula I is obtained by charging stearylamine, triethylamine and chloroform into a flask equipped with a stirrer, dropping 1.5 g of 1-chloro-2-methyl-2-propyl chloroformate thereinto under cooling with ice, continuing the stirring for 2 hr, then diluting the reactional solution with chloroform, washing the diluted reactional solution with water, dehydrating the washed solution, subsequently distilling off the chloroform under a reduced pressure and recrystallizing the prepared colorless powder from a mixed solvent of an ether with n-hexane.
