Since both macrocycles become equally nonplanar upon N - methyl substitution , the difference in the reactivities must be related to the electronic effects of substituents , which are transmitted to the nitrogen atoms of the CS through ...

At higher temperatures ( 700–870 K ) , samples with low hydrogen substitution levels have conductivities far higher than unsubstituted hydrogen phosphate has . Progress in substitution decreases the cationic conductivity in the ...
