Design and synthesis of a "starburst"-type nonadiazo compound and magnetic characterization of its photoproduct
A "starburst"-type nonadiazo compound was designed and synthesized by using the cyclotrimerization of 3,5-dibenzylphenyl ethynyl ketone as a key step.The diazo compound was photolyzed in methyltetrahydrofuran solid solution at cryogenic temperatures and a
Design, synthesis, and characterization of three kinds of π-cross-conjugated hexacarbenes with high-spin (S = 6) ground states
Three kinds of nonlinearly π-conjugated hexadiazo compounds were obtained from the corresponding hexaketones for which cyclotrimerizaton of the ethynyl ketones to form 1,3,5-triaroylbenzenes and deoxygenation of a calix[6]arene were key steps. The diazo c
PHOTOCHEMICAL PRODUCTION OF HIGHLY ORDERED SPINS IN ORGANIC SOLIDS
Poly(m-phenylenemethynyl)s and the related ?-conjugated polymers to which photolabile diazo groups are attached as pendants have been prepared.They were photolyzed and studied in situ by means of ESR spectroscopy and magnetometry on a Faraday magnetic bal
