Fe(II) triazole complexes have been attracting much interest due to their spin-crossover phenomenon which converts spin states by external stimuli. Recently, we have developed lipophilic Fe(II) triazole complexes which are disperse in organic media with maintaining the 1D polymer structures. To develop photofunctional Fe(II) triazole complexes in which fluorescence properties are regulated spin-crossover characteristics, we have newly synthesized lipophilic Fe(II) triazole complex [Fe(II)(1)3](Py-SO3 -)2 which contains 1-pyrenesulfonate ions as counter anions. The correlation between spin-crossover and fluorescent properties in the toluene solution state is investigated. This complex shows abrupt and reversible spin-crossover above room temperature in toluene. Interestingly, fluorescence intensity of pyrene chromophores incorporated on the surface of the 1D complex are highly quenched when Fe(II) ions are in the low spin state. Whereas, it is less quenched in the high spin state. Thus, photo relaxation processes of organic chromophores incorporated on the 1D Fe(II) triazole complex can be regulated depending on the spin-crossover characteristics.
