Ni–Co–Mn complexed 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA-NiCoMn) and its graphene in situ composites (PTCDA-NiCoMn-G) were prepared. The PTCDA-NiCoMn-G electrode has superior capacity, ICE, cycle and rate behavior compared to PTCDA-NiCoMn.
Perylene tetracarboxylic acid (PTCA) was prepared and employed as an ECL luminophore with K2S2O8 as the co-reactant, for the detection of folic acid on SPCE. A linear decrease in ECL intensity was observed with increasing folic acid concentration.
Weakly interacting systems such as organic molecules on monolayers of hexagonal boron nitride (h-BN) offer the possibility of single integer charge transfer leading to the formation of organic ions.
The PTCDA/g-C3N4 system, with three interfaces, not only effectively suppresses carrier recombination, facilitating the conversion of ˙O2− to 1O2, but also promotes the formation of products through the absorption of visible light.
This study shows that post-synthetic modification of UiO-66-NH2 with PTCDA-Na yields a fluorescent amide-linked MOF (UiO-66-NH-PTCDA-Na), which exhibits fluorescence quenching in the presence of Cu2+, Pb2+, and Fe3+ ions in HEPES buffer (pH 7.0).
