An L ‐proline‐derived amphiphilic squaraine dye displays unique self‐ assembly behavior in solution, forming new aggregates with large and symmetrical exciton splitting, while forming layered structures by an unprecedented “self‐templating” effect on graphite surfaces. This unusual aggregation behavior is most likely the result of the dye's chiral molecular structure (see figure). These observations should facilitate the design of related self‐assembled materials for (supra)molecular electronics.
