以4-磺基杯[4]芳烃为连接剂，对铂-二氧化钛进行表面修饰，成功地将阳离子染料分子(噻唑橙，TO)锚定在铂-二氧化钛表面，形成表面络合物(见图)。这种多相体系可以作为一种高效的光催化剂，在牺牲试剂(TEOA=三乙醇胺)的存在下产生氢气。
Successful anchoring of cationic dye molecules (thiazole orange, TO) on Pt‐TiO2 for a visible‐light‐harvesting assembly was achieved by surface modification of Pt‐TiO2 with 4‐sulfocalix [4] arene as a linker, leading to formation of surface complexes (see picture). This heterogeneous system can act as an efficient photocatalyst for production of hydrogen in the presence of a sacrificial reagent (TEOA= triethanolamine).
