文摘

In this study, phenoxy-adamantane substituted cyclophosphazene compounds (5-8) were synthesized in three steps. Firstly; adamantane derivatives (1 and 2) containing alkyne groups were prepared. Secondly; 2,2,4,4,6,6-hexzakis-(2¡ä-azido-1¡ä-ethoxy)-cyclotriphosphazatriene (3) and 2,2,4,4,6,6,8,8-octakis-(2¡ä-azido-1¡ä-ethoxy)-cyclotetraphosphazatetraene (4) were synthesized from the nucleophilic substitutions of 2-azido-1-ethanol with trimer (N₃P₃Cl₆) and tetramer (N₄P₄Cl₈) in THF respectively. Thirdly; cyclophosphazenes containing adamantane units (5-8) were obtained by the Cu(I) catalyzed click reactions of cyclophosphazenes (3 and 4) with compounds 1 and 2. The structural investigations of newly synthesized compounds 1-8 were evaluated by elemental analysis and FT-IR (ATR), mass spectrometry, ¹H, ¹³C, ¹H-¹³C HSQC (for 6) and ³¹P NMR (for 3-8) spectroscopies. Compound 1-8 were also reported for the first time. The thermal and photophysical properties of 5-8 were investigated.
