Luminescent infinite coordination polymers (CP) from metal-terpyridine ligation

General procedures, materials, and instrumentations. All airor water-sensitive reactions were carried out under a dry nitrogen atmosphere using standard Schlenk techniques. Fe and Ru ICP standards were obtained from Ricca Chemicals Co. (Arlington, TX). Unless otherwise stated, all chemicals and solvents were purchased from Aldrich Chemicals Co. (Milwaukee, WI) and used without further purification. Water was obtained from a deionized water source provided by Northwestern University. Deuterated solvents were purchased from Cambridge Isotope Laboratories (Andover, MA) and used without further purification. Dry solvents were prepared by passing HPLC-grade solvents through a column packed with neutral alumina via a Dow-Grubbs solvent system installed by Glass Contours (now SG Water USA, Nashua, NH). All dry solvents were collected under inert gases, degassed under vacuum, and stored under nitrogen in a Strauss flask prior to use. All the gases used for the adsorption and desorption measurements were Ultra High Purity Grade 5 and were obtained from Airgas Specialty Gases (Chicago, IL).
