1H-pyrazolo[3,4-b]quinoline and 1H-pyrazolo[3,4-b]quinoxaline derivatives as promising materials for optoelectronic applications

A review of recent studies of pyrazoloquinoline and quinoxaline derivative chromophore used as organic light emitting diodes and photovoltaic elements is done. We present both the principal ways of modifications of these materials as well as a possible chemical modifications to achieve more suitable technological parameters.
