“…It was shown that water-soluble POSS materials can encapsulate hydrophobic molecules inside these materials by adsorption onto the POSS surface via van der Waals interactions that originated from the extensive low polarity of the cubic silica core. [37][38][39][40][41][42][43] Based on this character, a detection system with 19 F nuclear magnetic resonance (NMR) probes was constructed for bio-active Figure 4 Chemical structures of POSS fillers having different types of alkyl substituents and changes in refractive indices (Δn), the thermal decomposition temperature with 20 wt% weight loss (ΔT d20 ) and rigidity of poly(methyl methacrylate) (ΔE′) by filler addition. (iC4+CP), (iC4+C18) and (CP+C18) indicates the modified POSS having different types of alkyl chains in the single core, and iC4&CP mix , iC4&C18 mix and CP&C18 mix were prepared by simply mixing with each octa-substituted POSS in the matrix (iC4: isobutyl, CP: cyclopentyl, C18: octadecyl groups).…”

An element-block is defined as a minimum functional unit composed of heteroatoms. The concept of 'element-block material' for designing advanced materials was proposed in 2015. In this review, the recent progress in material designs based on this concept is described. From our research, several element-blocks as representative examples are selected, and their roles in each material are explained. Initially, research on the development of 'designable hybrids' by employing polyhedral oligomeric silsesquioxane (POSS) is illustrated. Multiple functions of hybrids composed of modified POSS and the significant roles of POSS in bio-related polymeric materials for solving critical problems in conventional 19 F MR probes and for realizing new sensing technologies are demonstrated. Next, solid-state luminescent materials containing o-carborane and group 13 element-blocks are discussed. The materials' highly efficient emission in the solid state and their origins are explained. Furthermore, stimuliresponsive luminescent chromism is summarized. The sensing mechanisms and the application of these materials as sensors are presented in this study. In the last part, we mention optically active element-blocks containing chiral P-stereogenic phosphorus. In this review, the characteristics originating from each element-block are explained.
