Can conformational flexibility influence the self-assembly behavior and sensing efficacy of fluorogenic amphiphiles? A case study with bisbenzimidazole-based probes† In this work, we have explored the metal ion sensing properties of two bisbenzimidazole-based fluorescent probes, that differ in their conformational flexibility, in an aqueous medium.

Modulation in the charge transfer characteristics of flexible bis-benzimidazole probes: independent sensing mechanisms for Hg2+ and F−† Flexible bis-benzimidazole-based V-shaped amphiphilic probes (1 and 2) that form a fluorescent nanoscopic assembly in aqueous media have been designed. The ion-binding properties of compound 1 are investigated in both polar protic (water) and aprotic (acetonitrile) solvents.

Recently organic-doped polyethyleneimine based hydrogels have emerged as smart responsive materials for optical sensing applications. To this end, herein we have designed and synthesized a biocompatible fluorescent hydrogel based on polyethyleneimine (PEI), incorporating pyrene as the polyaromatic signaling moiety. The self-assembly properties of the composite materials were primarily influenced by the nature of the organic dopant, the degree of substitution, and the microenvironment.
