Time-resolved fluorescence of α,ω-di(1-naphthyl)oligosilanes and 1-naphthyloligosilanes: Intramolecular excimer formation and charge-transfer interactions

The intramolecular photochemical processes excimer formation and charge-transfer (CT) complex formation were investigated by comparing the behavior of α,ω-di(1-naphthyl)permethyloligosilanes ((1-naphthyl)-(SiMe2) n -(1-naphthyl); NS n N, n = 1, 3, and 6) and 1-(1-naphthyl)permethyloligosilanes ((1-naphthyl)-(SiMe2) n -Me; NS n, n = 1, 3, and 6) by use of stationary and time-resolved fluorescence (TR-FL) measurements. Formation of excimer and CT complexes is highly dependent on the silicon chain length and polarity of the medium. Graphical Abstract: Intramolecular excimer formation between the two naphthyl groups and charge transfer interactions between the naphthyl and silane moieties were investigated by use of a time-correlated single-photon counting method.[Figure not available: see fulltext.]

π-π and σ-π interactions in α,ω-Di-(9-anthryl) and Di-(1-naphthyl) oligosilanes studied by time-resolved fluorescence in solution

The photophysical properties of two series of oligosilanes, (1-naphthyl)-(SiMe2)n-(1-naphthyl) (1-5) and (9-anthryl)-(SiMe2)n-(9-anthryl) (6-10) with n = 1-4 and 6, were investigated. In these compounds, two types of interactions, a π-π interaction between two aromatic groups and a σ-π interaction between aromatics and a silicon chain unit, were observed. Intramolecular excimer emission was observed in cyclohexane when n ≥ 2. The strongest excimer emission of 2 and 7 is different from the Hirayama rule (n = 3) proposed for carbon analogues and also shows that intramolecular cycloaddition is minor. The time-resolved fluorescence spectra of an anthryl series revealed that the time constant of excimer formation varied depending on the chain length (82-152 ps). In the cases of 4, 5, and 10, charge-transfer (CT) emission was observed in acetonitrile or THF. The time constant of the CT-state formation for 10 was relatively slow (45 ps), which may indicate a conformational change. Monomer emission from the locally excited state was observed for 1 and 6 in both cyclohexane and acetonitrile.

?-? and ?-? Interactions in α,ω-Dinaphthyl and -Dianthryl Oligosilanes in Solution

The ?-? and ?-? interactions in α,ω-1-naphthyl and di-9-anthryl oligosilanes [Np-(SiMe2)n-Np (1-4), Ant-(SiMe2)n-Ant (5-8), n=1-4] were investigated in solution. In nonpolar solvents such as cyclohexane, a strong excimer fluorescence is observed, which indicates a strong ?-? interaction. In polar solvent (CH3CN), a charge-transfer (CT) emission is observed for 3 and 4 due to the ?-? interaction.
