Three carbonates of alcohols 1-3 were synthesized through condensation of 9-hydroxymethylacridine and chloroformates of alcohols, including benzyl alcohol, phenethyl alcohol and one galactose derivative. The photolysis of protected alcohols can efficiently release the corresponding alcohol in the efficiencies (Qulε) of 100-200 (quantum yield Qul=0.011-0.023, and molar absorptivity ε= 9.1 × 10^3-9.8 × 10^3 mol^-1·L·cm^-1) under 360 nm light.展开更多
