✦ Synopsis

The term 'ionic liquid' has come to indicate a class of molten organic salts that are liquid at room temperature and may contain bulky aromatic moieties such as imidazolium or heterocyclic pyridinium as cation and an inorganic anion such as PF 6 À , BF 4

À , [(CF 3 SO 2 ) 2 N] À , NO 3 À , etc. The room-temperature ionic liquids (RTILs) have some unique properties such as good electrical conductivity, negligiblevapour pressure, high ionic mobility, excellent electrochemical and thermal stability and a wide liquidus temperature range (À96 to 300 C) [1][2][3][4]. Various photophysical, theoretical and ultrafast spectroscopic studies have been done on RTILs [5][6][7][8][9][10][11][12][13].

Photoinduced electron transfer (PET) is one of the most fundamental reactions in biological, physical, inorganic and organic chemical systems. The theory regarding electron transfer was first proposed by Marcus [14], and the electron transfer rate can be written as Hydrogen Bonding and Transfer in the Excited State, Volume I & II
