We present a study of the process e+e−→ηϕ using data samples collected with the BESIII detector corresponding to an integrated luminosity of 15.03  fb−1 at 23 center-of-mass energies from 3.773 to 4.600 GeV. The Born cross sections are measured at each energy, and a coherent fit to cross section line shape is performed using a Breit-Wigner parametrization to search for charmoniumlike vector states. No significant signals of the Y(4230) and Y(4360) resonances are observed.
