In this report, the development of a new class of monocarboxylate functionalized cyanine derivatives using improved synthetic procedures is detailed. The employed synthetic strategy relies on efficient nucleophilic attack of alkyl-thiols on cyanine dyes bearing chloro-substituted polymethinic linkers. Monocarboxylate derivatized
