Improved photocurrent generation of three hybrid films made of [BW11Co(H2O)O39]7- and hemicyanines with alkyl linkers of varying length

Bipolar Hemicyanine-Based Photodynamic Modulation of Type I Pathway for Efficient Sterilization and Real-Time Monitoring

“…Hemicyanine derivatives are attractive components in materials with D−π–A structure, and have been extensively applied in nonlinear optical materials, fluorescent materials and photoelectric conversion systems because of their appealing chemical and photochemical properties, intense visible absorption, and easily modifiable structure. − Hemicyanine derivatives with positive charges have been reported to be effectively assembled with negatively charged component to easily obtain hybrid films with excellent photoelectric properties by electrostatic adsorption technology, but their applications in biomedical field are bare of development. On the basis of the conjugated structure and excellent photophysical properties, cationic hemicyanines are expected to effectively combine with negatively charged pathogenic microorganisms and exhibit satisfactory reactive oxygen species production capacity for phototoxicity concurrently with imaging monitoring.…”
