We further show that mithrene's highly efficient blue photoluminescence, ultrafast exciton radiative dynamics, as well as flexible tunability of molecular structure and optical properties demonstrate great potential of MOChas for constructing optoelectronic and quantum excitonic devices.Fusion pores serve as an effective mechanism to connect intracellular organelles and release vesicle contents during exocytosis. A complex lipid rearrangement takes place as membranes approximate, bend, fuse, and establish a traversing water channel to define the fusion pore, linking initially isolated chambers. Thermodynamically, the process is unfavorable and thought to be mediated by specialized proteins. In this work, we have developed a reaction coordinate to induce fusion pores from initially flat and parallel lipid bilayers and we have used it to describe the effects of the synaptotagmin-1 C2B domain during the process. We have obtained free-energy profiles of the whole lipid reorganization in biologically realistic membranes, going from planar and parallel bilayers through stalk hemifusion to water channel formation. Our results point to a lysine-rich polybasic region on synaptotagmin-1 C2B as the key to lipid reorganization control through the formation of phosphatidylinositol bisphosphate clusters that stabilize the fusion pore.A fluorescent probe for the monitoring of H2S levels in living cells and organisms is highly desirable. In this regard, near-infrared (NIR) fluorescent probes have emerged as a promising tool. NIR-I and NIR-II probes have many significant advantages; for instance, NIR light penetrates deeper into tissue than light at visible wavelengths, and it causes less photodamage during biosample analysis and less autofluorescence, enabling higher signal-to-background ratios. Therefore, it is expected that fluorescent probes having emission in t
