Abstract
This thesis can be divided into two major parts. The first part is the design, synthesis, and electrogenerated chemiluminescence (ECL) of a series of donor substituted phenylquinolinylethynes. We aim to study the effect of positional isomerism on their photophysical and ECL properties.In this context, we have chosen 3- and 4-(p-substituted phenyl) ethynylquinolines, and 1- and 4-(p-substituted phenyl) ethynylisoquinolines for studies. .
The second part of this thesis reports the electronic properties of pyrene (Py) derivatives, in which the Py group is conjugated with either electron donors (-PhNMe2, DMA and iPrOPh-, IPP) or electron acceptors anthronitrile, AN and 2-quinolinyl, 2Q) through an ethynyl bridge. The results are compared with the non-substituted system, namely, 1-phenylethynylpyrene (PhEPy). All the structures of arylethynylpyrenes (ArEPy’s) have been thoroughly characterized, and their electronic properties were studied by absorption and emission spectroscopies.
