We investigated a novel water‐soluble conjugated polymer (WSCP) for thiol detection based on "turn‐off" effect. This WSCP was modified with poly(ethylene glycol) (PEG) by disulfide linkages to achieve good solubility in aqueous solution (34 mg/mL) and high quantum yield (0.47). The separation of water‐soluble PEG chains from the conjugated backbone induced by the cleavage of the disulfide...
A novel water‐soluble fluorescent amphiphile based on amino polyethylene glycol (PEG‐NH2) substituted oligo(p‐phenyleneethynylene) (OPE) was designed and synthesized successfully. Taking anion OPE amphiphile as a comparison, the photophysical features were investigated through ultraviolet absorption (UV) and photoluminescence (PL) analyses. Due to the hydrophobic‐hydrophilic property of the OPE conjugated...
