description: Utilizing a data set of $6.7$ fb$^{-1}$ from electron-positron collisions recorded by the BESIII detector at the BEPCII storage ring, a search is conducted for the processes $e^{+}e^{-} \to ϕχ_{c0}$ and $ϕη_{c2}(1D)$ across center-of-mass energies from 4.47 to 4.95 GeV. In the absence of any significant signals, upper limits are set. These include limits on the Born cross sections for $e^{+}e^{-} \to ϕχ_{c0}$, as well as the product of the Born cross section for $e^{+}e^{-} \to ϕη_{c2}(1D)$ and a sum of five branching fractions. Furthermore, the product of the electronic width of $Y(4660)$ and the branching fraction of the $Y(4660) \to ϕχ_{c0}$, denoted as $Γ^{Y(4660)}_{e^{+}e^{-}} \mathcal{B}_{Y(4660) \to ϕχ_{c0}}$, is determined to be $&lt; 0.40$ eV at the 90\% confidence level.
