We report the synthesis of a set of 2Dmetal-organicframeworks (MOFs) constructed with organosilicon-based linkers. These oligosilyl MOFs feature linear Sin Me2n (C6 H4 CO2 H)2 ligands (lin-Sin , n=2, 4) connected by Cu paddlewheels. The stacking arrangement of the 2D sheets is dictated by van der Waals interactions and is tunable by solvent exchange, leading to reversible structural transformations

Conformation effect of oligosilane linker on photoinduced electron transfer of tetrasilane-linked zinc porphyrin–[60]fullerene dyads
fluorescence of the zincporphyrin moiety in each dyad was quenched by the electrontransfer to the fullerene moiety. The transient absorption measurements revealed that the final state of the excited-state process was a radical ion pair with a radical cation on the zincporphyrin moiety and a radical anion on the fullerene moiety as a result of the charge separation. The charge separation and charge recombination
