Solution Overview
Problem
The complex interplay of synthesis conditions and the use of templating agents in zeolite synthesis makes it challenging to predictively select suitable molecules for nanoporous host frameworks, leading to inefficient trial-and-error approaches in zeolite research.
Innovation Solution
A computer-implemented method that uses physics-based simulations to calculate a multi-factor index representing the affinity of molecules to nanoporous host frameworks, generating a binding matrix and ranking molecules based on their templating ability, which includes indices such as binding energy, competition energy, and directivity energy.

1Productivity
If traditional trial-and-error approach is used for zeolite synthesis, then research can proceed with simple methods, but the efficiency and predictability of molecule selection is poor
Solution Approach 1:
The patent performs preliminary computational screening and ranking of template molecules before actual synthesis experiments. By calculating binding energies and affinity scores in advance using simulated annealing simulations, the system identifies promising molecule-framework pairs ahead of time, allowing researchers to prioritize experiments based on predicted success rather than random trial-and-error.
Solution Approach 2:
The patent replaces the mechanical trial-and-error experimental approach with computational simulations. Using physics-based simulated annealing calculations, the system computes binding energies and affinity scores to predict synthesis outcomes, substituting physical experimentation with in-silico modeling to guide molecular selection.
2Reliability
If comprehensive simulation and ranking methods are implemented, then the predictability of synthesis outcome improves, but the computational complexity and resources required increase
Solution Approach 1:
The patent segments the complex molecule selection process into distinct computational stages: (1) performing simulated annealing simulations to calculate binding energies, (2) ranking molecules based on affinity scores, and (3) selecting top candidates for synthesis. This segmentation allows each step to be optimized independently and facilitates parallel processing of multiple molecule-framework pairs.
Solution Approach 2:
The patent transforms the synthesis prediction problem into a quantifiable computational task by changing parameters from qualitative experimental observations to quantitative binding energy values and affinity scores. By using computational chemistry parameters (energy calculations, binding affinities) instead of empirical trial results, the system achieves higher predictability through measurable, comparable metrics.

AI summary
A computer-implemented method calculates the affinity and templating ability of a molecule for a nanoporous host framework using a multi-factor index that uses simulation outcomes as component indices. Component factors of the multi-factor index may include, for example, binding energy, competition energy, and/or directivity energy. The multi-factor index may be used to analyze how known molecules template the formation of known frameworks.
