Four novel push−pull systems combining a central phenanthroline acceptor moiety and two substituted benzene rings, as a part of the conjugated π‐system between the donor and the acceptor moieties, have been synthetized through a straightforward and efficient one‐step procedure. The chromophores display high fluorescence and a peculiar fluorosolvatochromic behaviour. Ultrafast investigation by means
