Gold nanorods (GNRs) were encapsulated and dispersed into organic solvents by tetrabenzylthiol resorcinarene (TBTR) and by a poly(dithiocarbamate) derived from tetra-N-methyl(aminomethyl)resorcinarene (TMAR-DTC), formed by the in situ condensation of TMAR with carbon disulphide. The latter proved to be highly effective at enabling the redispersion of GNRs in various organic solvents. GNRs encapsulated in TMAR-DTC exhibited a strong solvatochromic response, with a refractive index sensitivity of more than 300 nm/RIU. The resorcinarene-encapsulated GNRs could withstand high temperatures for a short period of time, and could be used to nucleate the growth of magnetic nanoshells.

间苯二酚封装的金纳米棒：溶剂化显色性和磁性纳米壳的形成


金纳米棒（GNR）被四苄基硫醇间苯二酚（TBTR）和四-N-甲基（氨基甲基）间苯二酚衍生的聚（二硫代氨基甲酸酯）（TMAR-DTC）封装并分散到有机溶剂中，TMAR-DTC是由TMAR原位缩合形成的与二硫化碳。事实证明，后者在使 GNR 在各种有机溶剂中再分散方面非常有效。封装在 TMAR-DTC 中的 GNR 表现出强烈的溶剂化变色响应，折射率灵敏度超过 300 nm/RIU。间苯二酚封装的 GNR 可以在短时间内承受高温，并可用于成核磁性纳米壳的生长。
