ESIPT on/off switching and crystallization-enhanced emission properties of new design phenol-pyrazole modified cyclotriphosphazenes

A nucleophilic substitution reaction of N 3 P 3 Cl 2 (2,2′-dioxybiphenyl) 2 ( 1 ) with 2-(1 H -pyrazol-3-yl) phenol ( 2 ) was performed in order to synthesize molecules that may exhibit different photophysical properties on the cyclotriphosphazene scaffold. Bis-geminal phenol-pyrazole ( 3 ) and mono...
