Lemma 22.28.3. Let $R$ be a ring. Let $(A, \text{d})$ and $(B, \text{d})$ be differential graded algebras over $R$. The construction above defines an equivalence of categories

\[ \begin{matrix} \text{differential graded} \\ (A, B)\text{-bimodules} \end{matrix} \longleftrightarrow \begin{matrix} \text{right differential graded } \\ A^{opp} \otimes _ R B\text{-modules} \end{matrix} \]

Proof. Immediate from discussion the above. $\square$
