Abstract
An azonia cation has been explored for the first time as an acceptor unit in charged π-donor π-acceptor chromophores. Initial experimental and theoretical data show that quinolizinium, the simplest heteroaromatic azonia cation, behaved as a good acceptor unit and conferred promising nonlinear optical properties to simple push–pull cationic chromophores.
