Solvation Dynamics of DCM in Dipalmitoyl

Abstract—Solvation dynamics of 4-(dicyanomethylene)-2-methyl-6-(p-dimethylaminostyryl) 4H-pyran (DCM) in dipalmitoylphosphati-dylcholine (DPPC) vesicles in water is studied using picosecond emission spectroscopy. The solvation dynamics of DCM in DPPC vesicles is found to be bi-exponential with two components of 120^20 ps (20%) and 5.5^0.5 ns (80%). This indicates slow relaxation of the wate
