Photochemistry of an azido-functionalized cryptand: Controlling the reactivity of an extremely long-lived singlet aryl nitrene by complexation to alkali cations

Bucher, G.; Tönshoff, C.; Nicolaïdes, Andrew N. (2005)

Photolysis of the cryptand 1, bearing an intraannular azido substituent, results in a complex photochemistry. Low-temperature photolysis yields the triplet nitrene 32, which has been characterized by EPR spectroscopy. Small ...

Thermoelectric properties and site-selective Rb+/K+ distribution in the K2-xRbxBi8Se13 series

Kyratsi, Theodora; Chung, D. Y.; Ireland, J. R.; Kannewurf, C. R.; Kanatzidis, M. G. (2003)

β-K2Bi8Se13 possesses promising thermoelectric properties whereas Rb2Bi8Se13 does not. The formation of solid solutions between these two compounds was attempted to study the alkali metal distribution in the structure and ...
