Abstract

Metal-organic frameworks are a class of emerging materials, with novel, designable, and outstanding properties. Terahertz (THz) spectroscopy is a versatile technique to explore low-energy resonant modes in these materials, and conductivity and photoconductivity. Understanding mechanism and timescales of photoconductivity in metal-organic frameworks (MOFs) is crucial for their applicability in solar energy generation. The subps time resolution of optical pump-THz probe (OPTP) in combination with time-resolved THz spectroscopy (TRTS) provides an unmatched view into the life of a photoelectron within MOFs. In this talk, I will present our experiments studying conductivity and photoconductivity in two MOFs, namely di-Zn(II)-tetrathiafulvalene-tetrabenzoate (Zn <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> TTFTB) and di-Mn(II)-2,5-dimercaptoterephthalate (Mn <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> DSBDC).
