Outline of Final Research Achievements

C4-unsubstituted 2,6-dicyano-λ5-phosphinine was excellently prepared. Versatile syntheses of λ5-phosphinines were developed starting from the C4-unsubstituted phosphinine by using both C4-selective electrophilic substitutions and the following conversions. The phosphinines show distinct fluorescence both in solution and solid state. The photophysical properties can be tuned by electronic modification of the substituent. Some of those compounds can be applied as fluorescent chemical sensing molecules.
