abstract = {Bare (1) and silica coated (1@SiO2) spin crossover (SCO) nanoparticles based on the polymer {[Fe
(NH2Trz)3](BF4)2}n have been prepared following a water-in-oil synthetic procedure. For 1, the critical
temperatures of the spin transition are TC↓ = 214.6 K and TC↑ = 220.9 K. For 1@SiO2, the abruptness of
the transition is enhanced and the critical temperatures are centred at room temperature (TC↓ = 292.1 K
and TC↑ = 296.3 K). An inert Re(I) complex of formula [Re(phen)(CO)3(PETES)](PF6) (phen = 1, 10-phenanthroline;
PETES = 2(4-pyridylethyl)triethoxysilane) (Re) was also synthesized yielding intense green emission
centred at λem = 560 nm. The grafting of this complex on the silica shell of 1@SiO2 led to a bifunctional
SCO-luminescence composite (1@SiO2/Re) whose luminescence properties were tuned by the
spin state switching. Temperature-variable photophysical studies showed that luminescence and spin
transition were synchronized through a radiative (trivial) energy transfer mechanism between the Re(I) and
the Fe(II)-LS (LS, Low Spin) centres.},
