Lucensosergia lucens is a luminous marine shrimp that has been suggested to use a coelenterazine-dependent luminescence system. However, the genetic information related to the luminescence system is lacking. Our RNA-Seq analysis of this shrimp did not show the existence of known or homologous coelenterazine-dependent luciferase genes. Subsequent biochemical analyses suggested that the shrimp possessed unknown proteinaceous components for coelenterazine luminescence.

Covalent organic frameworks (COFs) have been emerging as versatile reticular materials due to their tunable structures and functionalities, enabled by precise molecular engineering at the atomic level. While the integration of multiple components into COFs has substantially expanded their structural complexity, the strategic engineering of diverse functionalities within a single framework the random distribution of linkers with varying lengths remains largely unexplored. Here, we report a series of highly crystalline mixed-length multivariate COFs synthesized using azobenzene and bipyridine as linkers, where tuning the ratio of linkers and incorporating palladium effectively modulates the balance between near-infrared (NIR) light absorption and catalytic sites for NIR-generation of hydrogen peroxide (HO).

A novel aggregation-induced emission (AIE) system with superior performance was successfully developed through local chemical modification from thiophene to thiophene sulfone. This approach, leveraging easily accessible tetraphenylthiophene precursors, dramatically enhances the photophysical properties in a simple oxidation step. Notably, the representative 2,3,4,5-tetraphenylthiophene sulfone (3c) demonstrates remarkable solid-state emission characteristics with a fluorescence quantum yield of 72% and an AIE factor of 240, substantially outperforming its thiophene analog.

The synergistic effect of various ions with optical properties is an important method to regulate the Er ion upconversion luminescence process. However, the energy processes between them are complicated and difficult to separate, and it is challenging to clarify the results of each process when multiple ions are co-doped. Herein, a series of NaYF:Er were synthesized by the low-temperature combustion method, and the luminescence color of Er ions was modulated by doping Yb ions and Tm ions.

Electrochemiluminescence (ECL) imaging through closed bipolar nanoelectrode arrays (BPnEAs) has emerged as a promising method for in situ label-free wide-field electrochemical imaging. In this study, a cathodic ECL system based on [Ru(bpz)]/SO is combined with the BPnEAs fabricated on silicon nitride membrane windows through focused ion beam nanofabrication, enabling effective bipolar imaging of heterogeneous anodic electrocatalytic reactions. The shape, distribution, size, and material composition of individual electrodes within the array can be precisely controlled.

Background: Of the mycotoxins, aflatoxin is the most significant. The detection of aflatoxin B1 (AFB1) is crucial for ensuring food safety, as this highly carcinogenic toxin readily contaminates crops such as grains and nuts, and timely detection can effectively prevent associated health risks. The selection of luminophores is of paramount importance in the detection of ECL (electrochemiluminescence).
