Molecular Relational Learning (MRL), aiming to understand interactions
between molecular pairs, plays a pivotal role in advancing biochemical
research. Recently, the adoption of large language models (LLMs), known for
their vast knowledge repositories and advanced logical inference capabilities,
has emerged as a promising way for efficient and effective MRL. Despite their
potential, these methods predominantly rely on the textual data, thus not fully
harnessing the wealth of structural information inherent in molecular graphs.
Moreover, the absence of a unified framework exacerbates the information
underutilization, as it hinders the sharing of interaction rationale learned
across diverse datasets. To address these challenges, this work proposes a
novel LLM-based multi-modal framework for Molecular inTeraction prediction
following Chain-of-Thought (CoT) theory, termed MolTC, which can efficiently
integrate rich graphical information of molecular pairs. For achieving a
unified MRL, MolTC innovatively develops a dynamic parameter-sharing strategy
for cross-dataset information exchange, and introduces a Multi-hierarchical CoT
principle to refine training paradigm. Our experiments, conducted across twelve
varied datasets involving over 4,000,000 molecular pairs, demonstrate the
superiority of our method over current GNN and LLM-based baselines. On the top
of that, a comprehensive Molecular Interactive Instructions dataset is
constructed for the development of biochemical LLM, including our MolTC. Code
