Untapped toolbox of luminol based polymers

Abstract

The objective of the current Perspective article is to highlight the present state of luminol based polymers, with a specific emphasis on how to include luminol derivatives into polymer chains...

Cellulose-Based Fluorescent Material for Extreme pH Sensing and Smart Printing Applications

“…UV–vis experiments further verified the chemical anchoring of the fluorophore onto the cellulose acetate backbone, resulting in the target molecule Lum-MDI-CA. The strong peaks at 360 and 298 nm are observed in the Lum fluorophore which belongs to the n−π* transition in the −CO group of Lum. − However, after chemically anchoring Lum, these peaks are shifted to 352 and 338 nm in Lum-MDI-CA, demonstrating n−π* transition due to −CO groups and π–π* transitions due to aromatic ring electrons of Lum-MDI-CA (Figure S1). In addition, the 1 H NMR spectrum (Figure E) also verified these results.…”

The Vibrant Interplay of Light and Self‐Reporting Macromolecular Architectures

“…CL reactions have received interest in diverse fields, for example, biomedical or analytical applications, with ongoing research for persistent advances. [ 59 ] Most CL probes (luminol [ 60 ] and peroxyoxalates (POs) [ 61 ] shown in Scheme A,B) deliver light emission upon reaction with an oxidizing agent (such as H 2 O 2 ), besides 1,2‐dioxetane (Scheme 2C) [ 62 ] derivatives that are specifically activated by a chemical of interest (reactive oxygen species, ROS, or enzyme derivatives). Generally, the former two classes of probes undergo an oxidation step to form an unstable strained peroxide, which in turn rapidly decomposes to generate an emissive species in its excited state that decays to its ground state through emission of light.…”

“…CL reaction pathways of A): luminol; [ 60 ] B): POs in the presence of a fluorophore; [ 61 ] and C): Schaap’ dioexetane probe. [ 62 ] …”

“…[ 68 ] In contrast to conventional bases, organic superbases (such as 1,5,7‐triaza‐bicyclo‐[4.4.0]dec‐5‐ene, TBD) allow the synthesis of monomers for the implementation within multi‐functionalized polymers and have paved the way for the development of polymer self‐reporting CL‐systems. [ 16 ] Indeed, the limited number of synthetic methodologies that have been developed for preparing luminol containing polymers [ 60 ] has restricted the application of polymer luminol derivatives as self‐reporting materials for long time. Consequently, a copolymer possessing luminol and the superbase was synthesized via sequential free radical polymerization of pentafluorophenyl acrylate (PFPA) and 4‐vinyl benzylchloride (VBC) in the presence of methyl methacrylate, and subsequent orthogonal post‐polymerization modification.…”

Exploiting poly(safranine) and poly(luminol) for sensing applications. A mini review

“…By virtue of the need for an inclusive overview of such polymers, both safranine and luminol polymeric moieties systems have infrequently been explored. 6,7 Over and above, the distinguishing chemical characteristics of their polymers are essential to understand since these characteristics of the designated polymers have multiple applications and potentials, from electro and biosensors to biomedicine.…”
