摘要: Abstract In the present work, new cyclotriphosphazene derivatives, {[N3P3(biph)(R)4] (biph = 2′,2″-dioxy-1′,1″-biphenyl, R = imidazolyl (5) and benzimidazolyl (7)}, were synthesized for first time. Both of these compounds (5 7) fully characterized by elemental analysis, mass spectrometry 1H 31P NMR spectroscopy. The crystal structures 5 7 determined single-crystal X-ray crystallography. Furthermore, a second polymorph (triclinic form) 2,2-monospiro-(2′,2″-dioxy-1′,1″-biphenyl)-4,4,6,6-tetrachlorocyclotriphosphazene (3) was isolated during course our study. UV–Vis absorption fluorescence emission properties 3, in range different solvents.
