A series of new D-π-A chromophores containing a triphenylamine fragment as a terminal electron-donating group, as well as (5,5-dimethylcyclohex-2-en-1-ylidene) propanedinitrile or (6-methyl-4H-pyran-4-ylidene) propanedinitrile fragments as an acceptor. A comparative analysis of the optical and electrochemical properties of the obtained compounds is carried out. It was found that the replacement of the (5,5-dimethylcyclohex-2-en-1-ylidene) propanedinitrile fragment with a (6- methyl-4H-pyran-4-ylidene) propanedinitrile fragment leads to a slight increase in the bandgap of the compound, while the coefficient increases significantly molar absorption, as well as the quantum yield of luminescence.
