Electrocrystallization of low dimensional solids: Directed selectivity and investigations of crystal growth with the quartz crystal microbalance

Research output: Contribution to journalArticle

Abstract

Electrocrystallization of charge transfer salts is described with regard to electrochemically directed stoichiometry and fundamental studies of nucleation and crystal growth. The stoichiometry of charge transfer solids can be controlled by the electrochemical potential during crystal growth of [(Cp{black star}Ru)266- [22] (1, 4) cyclophane)]2+[TCNQ]x2- (x = 2,4), with more anodic potentials yielding the mixed valent (x = 4) salt. Quartz crystal microbalance (QCM) studies allow measurement of the mass of crystalline salts during electrocrystallization, facilitating determination of rates of crystallization and Faradaic efficiencies. QCM studies of nucleation and crystal growth of TTFBr0.7 indicate kinetic barriers to electrochemical reduction of TTFBr0.7 deposits.
