AI Article Synopsis
- This text discusses how immobilizing molecular catalysts can enhance their activity by controlling the geometry of their active sites.
- It introduces a method using nonlinear scaling relationships to relate the spatial configuration of acid-base components in frustrated Lewis pairs (FLPs) to their effectiveness in catalyzing hydrogenation of CO.
- The findings reveal that precisely positioning and orienting the donor-acceptor centers significantly boosts the catalytic performance of FLPs compared to unconstrained ones.
Article Abstract
The immobilization of molecular catalysts imposes spatial constraints on their active site. We reveal that in bifunctional catalysis such constraints can also be utilized as an appealing handle to boost intrinsic activity through judicious control of the active site geometry. To demonstrate this, we develop a pragmatic approach, based on nonlinear scaling relationships, to map the spatial arrangements of the acid-base components of frustrated Lewis pairs (FLPs) to their performance in the catalytic hydrogenation of CO . The resulting activity map shows that fixing the donor-acceptor centers at specific distances and locking them into appropriate orientations leads to an unforeseen many-fold increase in the catalytic activity of FLPs compared to their unconstrained counterparts.
