      <subfield code="a">The development of organic materials with 2PA has attracted intensive attention in the past two decades [1]. In two-photon bio-imaging applications the design of the chromophore requires to have a good cross-section (σ2PA) and good biological compatibility which depends on the molecular volume and polarity [2].&#xd;
In this work, we present the design, synthesis and characterization of new indolium&#xd;
derivatives. These compounds are easy to achieve with good yields and good photophysical&#xd;
properties. In addition, time-dependent density functional theory (TDDFT) has been carried out to&#xd;
investigate the energy level of the ground and excited state.&#xd;
Their spectral properties and assays performed on cultured cells, demonstrate the potential&#xd;
of these compounds as fluorescent probes with application in two-photon bio-imaging.</subfield>
