At the end of July 2026, the "Innovation and Future of Silsesquioxane Chemistry" International Conference and Summer School was held at Shandong University. The event brought together over 40 international representatives from more than 10 countries and regions, including Russia, the United States, France, Poland, Japan, and South Korea, as well as more than 120 experts, scholars, corporate delegates, and early-career researchers from 33 domestic universities and the silicone industry.

Three Major Frontier Achievements Draw Attention

According to reports from Science and Technology Daily, several leading international scholars presented disruptive research findings at the conference:

Achievement 1: A New Understanding of σ–σ Conjugation.* Professor Richard M. Laine of the University of Michigan, USA, presented research on "Polysiloxanes Achieving σ–σ* Conjugation via Si–O–Si Bonds," challenging conventional wisdom in silicone chemistry. This discovery could redefine the development pathway for optoelectronic properties of silicone materials.

Achievement 2: "Cycloless" Catalytic Polymerization. Professor Kato Takeshi of the University of Toulouse, France, pioneered a "cycloless" catalytic polymerization technology for silicone rubber, overcoming a half-century industrial challenge. Should this technology reach industrial scale, it could transform the synthetic process route for silicone rubber, mitigate environmental compliance pressures associated with cyclic residue, and offer a brand-new solution for the synthesis of silicone rubber free of D4/D5/D6 residues.

Achievement 3: High-Entropy Silicone Systems. Professor Robert E. Przybkop of Adam Mickiewicz University in Poznań, Poland, proposed a materials design concept for high-entropy silicone systems, providing a theoretical framework for developing novel silicone materials with extreme performance characteristics.

AI Reshaping the Paradigm of Chemical Research

Professor Liu Hongzhi of Shandong University, who chaired the conference, noted that AI is fundamentally reshaping the underlying logic of chemical research—from molecular design and reaction prediction to data-driven materials discovery, with no exception. The conference was structured around three main tracks: a high-level forum, a young scientists forum, and an international industry–academia–research special session, featuring 23 expert presentations and 31 early-career researcher reports, and additionally included an open discussion segment titled "Challenges and Responsibilities of Silsesquioxane Chemistry."

Implications for Downstream Enterprises

For technical personnel in silicone rubber product manufacturing, the key signal from this conference is that cutting-edge fundamental research is accelerating its evolution toward industrialization. The "cycloless" catalytic polymerization technology, in particular, if scaled up for commercial application, will directly impact the purity, environmental compliance, and production costs of silicone rubber raw materials. It is recommended that relevant companies monitor the subsequent industrialization progress in this field and conduct early assessments of the potential impact of technological shifts on raw material procurement and process routes.
