Star‐shaped molecules with a gradually varied number of peripheral acceptors were designed, synthesized, and subsequently investigated by using differential scanning calorimetry, electrochemistry, and linear absorption and emission spectra. Two‐photon absorption properties were studied by two‐photon absorption fluorescence. Experimental data were completed by the results of quantum chemical calculations and thorough structure‐property relationships were elucidated. The performed analysis showed that structural features such as the number of CN groups, star‐shaped arrangement, π‐linker composition, and multipodality are the most important factors affecting optoelectronic features of the studied chromophores.
