A promising strategy to design crosslinked photoluminescent hydrogel (PL hydrogel) is to synthesize the covalently
bonded polymer chains by thermal polymerization. A proper ratio of methacrylic acid and m-phenylenediamine was used to prepare
the PL hydrogel, and doping with graphene oxide and carboxymethyl chitosan improves the structure of the gel. The green and effi-
cient hydrothermal synthesis realized a high polymerization and a short reaction time. Meanwhile, a series of properties were investi-
gated for several combinations of hydrogels. Ultraviolet spectra, fluorescence spectra, and particle size distributions were used to
characterize the PL composites. Scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectros-
copy, thermogravimetric analysis, rheological studies, and stress–strain tests were conducted to characterize the morphology, structure,
and performance of the compound hydrogel. The adsorption properties of the PL hydrogel were characterized in adsorption tests.
The results indicated that the PL hydrogel exhibited a favorable luminescence property, a certain degree of mechanical strength, and
good adsorption performance. The prepared PL hydrogel has potential applications in adsorption and visual detection.

Smart hydrogels, a class of stimulus-responsive (SR) poly-
mers, have been broadly studied in recent years because of their
promising potential in manufacturing intelligent controllable
materials, which can display rapid and significant responses to
environmental stimuli, such as temperature, ion strength, pH,
light, salt, electricity, magnetism, and chemical substances.
the biomedical field, smart hydrogels have lots of practical appli-
cations, such as in temperature- and pH-responsive dendrimer
systems used to encapsulate and release drugs.
gels possess other potential practical applications, like in sensors,
molecular imprinting, protein recognition, enzyme immobiliza-
tion, and separation of biological molecules or cells.
Carboxymethyl chitosan (CMC), a hydrosoluble chitosan, has
been chosen as a superior candidate for fabricating smart
hydrogels on account of its hydrophilicity, biocompatibility, and
Amine-containing conjugated polymers have
been widely studied as purification agents in recent years.
example, poly(m-phenylenediamine) (PmPD), a classic amine-
containing conjugated polymer, was considered as a peculiar
adsorbent and dissolution agent due to its powerful coordina-
tion and assembly ability.
Most importantly, rich amino
sites made it highly reactive.

Graphene oxide (GO) has inspired great enthu-
siasm because of its thermal properties, electrical conductivity,
high stiffness and strength, and biocompatibility.
It is a hydro-
philic, dispersive material and is modified for improving the
mechanical strength of hydrogels due to abundant oxygen-
containing groups (ACOOH, AOH, and epoxy groups).
