DESCRIPTION:Xiaoting Zhang\, a doctoral candidate in chemistry\, will defen
 d their dissertation titled “Epitaxial Growth of Metal-Organic Framework Th
 in Films by Electro-Conversion and Electrodeposition.” Their advisor\, Dr. 
 Jay Switzer\, is a curators’ distinguished professor emeritus in the chemis
 try department. The dissertation abstract is provided below.\n\nElectrochem
 ical epitaxy is a facile and inexpensive soft-solution process to fabricate
  highly ordered thin films. This research focuses on the epitaxial growth o
 f metal-organic framework (MOF) thin films by electrochemical methods which
  include electro-conversion and electrodeposition.\n\nFirst\, an electroche
 mical conversion pathway was invented to achieve epitaxial MOF thin films. 
 Epitaxial single-domain Cu-BTC(111) thin films were manufactured by electro
 chemical oxidation of Cu2O(111) films electrodeposited on single-crystal Au
 (111). The single-crystal-like Cu-BTC(111) thin films with out-of-plane and
  in-plane order provide well-aligned 3.5 Å triangular windows along the [11
 1] direction. Cu-BTC(111) foils were fabricated from the Cu-BTC/Cu2O system
  by electrochemical etching and epitaxial lift-off. Epitaxial two-domain Cu
 -BTC(111) films and textured Cu-BTC(111) films were produced by using low-c
 ost and highly scalable substrates\, Au on Si and Au on glass\, respectivel
 y.\n\nSecond\, a direct electrodeposition strategy was developed to attain 
 epitaxial MOF thin films. Epitaxial Cu-BTC(100) thin films were electrodepo
 sited from a water/ethanol solution on single-crystal Au(100). Epitaxial Cu
 -BTC(111) thin films were also electrodeposited on single-crystal Au(111) w
 ith Cu2O as a buffer layer. The single-crystal-like Cu-BTC(100) thin films 
 without-of-plane and in-plane order provide well-aligned 9 Å square windows
  along the [100] direction. The single-crystal-like Cu-BTC(111) thin films 
 with out-of-plane and in-plane order provide well-aligned 3.5 Å triangular 
 windows along the [111] direction.
